U.S. rationale The official U.S. rationale for the invasion was articulated by President Bush on the morning of December 20, 1989, a few hours after the start of the operation. Bush cited Panama's declaration of a state of war with the United States and attacks on U.S. troops as
justification for the invasion. Bush further identified four objectives of the invasion: • Safeguarding the lives of U.S. citizens in Panama. In his statement, Bush stated that Noriega had declared that a state of war existed between the U.S. and Panama and had threatened the lives of the approximately 35,000 U.S. citizens living there. There had been numerous clashes between U.S. and Panamanian forces; one U.S. Marine had been killed a few days earlier. • Defending democracy and human rights in Panama. • Combating drug trafficking. Panama had become a center for drug money laundering and a transit point for drug trafficking to the U.S. and Europe. • Protecting the integrity of the Torrijos–Carter Treaties. Members of
Congress and others in the U.S. political establishment claimed that Noriega threatened the neutrality of the Panama Canal, and that the U.S. had the right under the treaties to intervene militarily to protect the canal. U.S. forces were instructed to begin maneuvers and activities within the restrictions of the Torrijos-Carter Treaties, such as ignoring PDF roadblocks and conducting short-notice "Category Three"
military exercises on security-sensitive targets, with the express goal of provoking PDF soldiers. U.S.
SOUTHCOM kept a list of abuses against U.S. servicemen and civilians by the PDF while the orders to incite PDF soldiers were in place. that this declaration referred to a state of war directed by the U.S. against Panama, in the form of what he claimed were harsh
economic sanctions and provocative military maneuvers (Operations Purple Storm and Sand Flea) that were prohibited by the Torrijos-Carter Treaties. Bush's four reasons for the invasion provided sufficient justification to establish bipartisan Congressional approval and support. However, the secrecy before the invasion's initiation, the speed and success of the invasion itself, and U.S. public support for it (80% public approval) did not allow
Democratic lawmakers to object to Bush's decision to use military force. Ground forces consisted of: • combat elements of the

Operation description The U.S. invasion of Panama began on December 20, 1989, at 12:46 a.m. local time. The operation involved 27,684 U.S. troops and over 300 aircraft, including
C-130 Hercules tactical transports flown by the
317th Tactical Airlift Wing (which was equipped with the Adverse Weather Aerial Delivery System or AWADS) and
314th Tactical Airlift Wing,
AC-130 Spectre gunships,
OA-37B Dragonfly observation and attack aircraft,
C-141 Starlifter and
C-5 Galaxy strategic transports,
F-117A Nighthawk stealth ground-attack aircraft flown by the
37th Tactical Fighter Wing, and
AH-64 Apache attack helicopters. The invasion was the first combat deployment for the AH-64, the
HMMWV, and the F-117A. Panamanian radar units were jammed by two
EF-111As electronic warfare aircraft of the 390th ECS, 366th TFW. These aircraft were deployed against the 16,000 members of the PDF. The operation began with an assault of strategic installations, such as the civilian
Punta Paitilla Airport in Panama City and a PDF
garrison and airfield at
Rio Hato, where Noriega also maintained a residence. Navy SEALs destroyed Noriega's private jet and sank a Panamanian
gunboat. A Panamanian ambush killed four SEALs and wounded nine. Other military command centers throughout the country were also attacked. C Company 1st Battalion (Airborne) 508th PIR was assigned the task of securing
La Comandancia, the central headquarters of the PDF. This attack touched off several fires, one of which destroyed most of the adjoining and heavily populated El Chorrillo neighborhood in
Panama City. During the firefight at
La Comandancia, the PDF downed two special operations helicopters and forced one
MH-6 Little Bird helicopter to crash-land in the Panama Canal. the first and only time they were
air dropped in a combat zone. Four of them had been transported in secret to Howard Air Force Base aboard a
C-5 Galaxy in November, while other 10 were parachute dropped by a
C-141 to
Torrijos-Tocumen Airport several hours into the invasion. A platoon from the
1138th Military Police Company,
Missouri Army National Guard, which was on a routine two-week rotation to Panama, was called upon to set up a detainee camp on Empire Range to handle the mass of civilian and military detainees. This was the first National Guard unit called into active service since the
Vietnam War.
Capture of Noriega Operation Nifty Package was an operation launched by Navy SEALs to prevent Noriega's escape. They sank his boat and destroyed his jet, at a cost of four killed and nine wounded. Military operations continued for several weeks, mainly against PDF units. Noriega remained at large for several days, but realizing he had few options in the face of a massive manhunt and a $1 million reward for his capture, he obtained refuge in the
Apostolic Nunciature of the diplomatic mission of the
Holy See in Panama City. However, the U.S. military's psychological warfare pressure on Noriega was relentless, reportedly with the playing of loud rock-and-roll music day and night in the densely populated area surrounding the Holy See mission. A report of the Office of the Chairman of the
Joint Chiefs of Staff claimed that the music was used principally to prevent
parabolic microphones from being used to eavesdrop on negotiations and not as a
psychological weapon based around Noriega's supposed loathing of rock music. Noriega finally surrendered to U.S. forces on January 3, 1990. He was immediately put on an
MC-130E Combat Talon I aircraft and flown to the United States.
Casualties picks up a Marine casualty According to official Pentagon figures, 516 Panamanians were killed during the invasion, including 314 soldiers and 202 civilians; The
United Nations estimated 500 civilian deaths, whereas
Americas Watch estimated 300 civilian deaths. President Guillermo Endara said that "less than 600 Panamanians" died during the entire invasion. Former
U.S. Attorney General Ramsey Clark estimated 3,000 civilian deaths. The
Roman Catholic Church estimated that 673 Panamanians were killed in total.
Physicians for Human Rights said it had received "reliable reports of more than 100 civilian deaths" that were not included in the U.S. military estimate but also that there was no evidence of several thousand civilian deaths. According to
The New York Times, figures estimating thousands of civilian casualties were widely rejected in Panama. U.S. military casualties in the invasion were 23 killed and 325 wounded. In June 1990, the U.S. military announced that of its casualties, 2 dead and 19 wounded were victims of
friendly fire. The number of Panamanian military dead was estimated at 314 by SOUTHCOM. The U.S. government again rejected the claim, disputing both its liability for warzone deaths in general and whether Rodriguez had been killed by U.S. rather than Panamanian gunfire. Captain
Linda L. Bray, commander of the 988th Military Police Company of
Fort Benning,
Georgia, led her troops in a three-hour firefight against PDF troops who refused to surrender a dog kennel which (it was later discovered) they were using to store weapons. Bray was said to be the first woman to lead U.S. troops in battle, and her role in the firefight led to controversy in the media and in Congress over women's roles in the U.S. military. Bray requested and received a discharge in 1991. First Lieutenant Lisa Kutschera and Warrant Officer Debra Mann piloted
UH-60 "Blackhawk" helicopters ferrying infantry troops. Their helicopters came under fire during the invasion, and like their male counterparts, both women were awarded
Air Medals for their roles during the invasion. The traditional role of women in wars had also seen a transformation during the invasion. Besides being combat medics and logisticians, many women took on support roles and provided crucial support that facilitated the operational objectives. This included roles in transportation, supply chain management, and intelligence. Outside of the battlefield, female journalists and reporters expansively covered the invasion, providing critical information to the public and bringing international attention to the events unfolding in Panama. These perspectives and the subsequent public discussion eventually led to the shaping of the public perception of the U.S. military action.
Origin of the name "Operation Just Cause" Operation plans directed against Panama had evolved from plans designed to defend the Panama Canal. They became more aggressive as the situation between the two nations deteriorated. The
Prayer Book series of plans included rehearsals for a possible clash (Operation Purple Storm) and missions to secure U.S. sites (Operation Bushmaster). The original operation, in which U.S. troops were deployed to Panama in early 1989, was called Operation Nimrod Dancer. Eventually these plans became Operation Blue Spoon, renamed Operation Just Cause by the Pentagon to sustain the perceived legitimacy of the invasion.
General Colin Powell said that he liked the name because "even our severest critics would have to utter 'Just Cause' while denouncing us." Critics, however, renamed it Operation "Just 'Cuz," arguing that it had been undertaken "just [be]cause Bush felt like it." The post-invasion civil-military operation designed to stabilize the situation, support the U.S.-installed government, and restore basic services was originally planned as Operation Blind Logic, but was renamed "Operation Promote Liberty" by the Pentagon on the eve of the invasion. == Legality ==
