Actually...AMERICA holds a grudge against japan for their unprovoked attack on pearl harbor.
Americans seem to hold a grudge against Canada for not joining in on the Iraq war, although Canada did more than most think. Every week there is some piss-ant baging on Canada.
Canadians helped by
Leading the Coalition's Navy
Canada led the multinational naval taskforce in the Persian Gulf. Some 1,300 Canadian troops, aboard Canadian warships, rallied to protect U.S. aircraft carriers so they could "safely" position themselves to launch air strikes against Iraq.
Coordinating Air Battles
Canadian military personnel aboard E-3 AWACs aircraft helped to direct the war. E-3 aircraft are mobile nerve centres of modern air war. Canadian crews helped coordinate and manage air battles, and filled command, weapons control and communications roles.
Providing War Planners
Canadian war planners worked among the war strategists at U.S. Central Command (CentCom) headquarters at McDill Air Force Base, Florida. At least two dozen of these Canadian war strategists moved with CentCom when it relocated to the Persian Gulf, just before the war.
Providing Military Transport Planes
At least three Canadian CC-130 military transport planes were listed by the U.S. military as having helped to supply coalition forces during the war.
Parts and Services for Major Weapons
At least 100 Canadian corporations contributed components and/or services for at least 35 of the major weapon systems that were used in the latest Iraq war. Index listing Canadian corporations and the major weapons delivery systems that they provided with components and/or services
Welcoming U.S. War Planes
U.S. warplanes have Canadian government permission to:
(1) fly through Canadian airspace to and from the war,
(2) stop over for refuelling in Newfoundland and PEI,
(3) conduct low-level, training and bombing exercises through seven "flight corridors" in Canada.
Freeing up Troops
By providing extra troops for the U.S.-led war in Afghanistan, Canada freed up U.S. troops for the Iraq war.
On numerous occasions, Canadian government officials gave diplomatic support for the war. For instance, Prime Minister Chrétien (even though this guy is a moron) said that the U.S. had a "right" to go to war with Iraq, and that Canadians should not question the war because this gives comfort to Saddam Hussein.
In 2002 alone, Canadian contractors sold about US$440 million worth of military equipment to the U.S. The vast majority of this hardware was used in the Iraq war. Links to data on 33 major weapons delivery systems used in current Iraq war, with Canadian components &/or services
(1) Two types of cruise missiles (AGM-86 and AGM-129) were tested in Canada, 1983-1994.
September 1st 1939, Germany invaded Poland without warning. By the evening of September 3rd, Britain and France were at war with Germany and within a week, Australia, New Zealand, Canada and South Africa had also joined the war. The USA did not join until December 4th 1941. 2 years later. No grudge was held then . Allied forces were happy for the help in a war that could have ended sooner.
