What if The United States went to war with Canada?

This is an idea that I have been floating around in the back of my mind for a while, and I finally decided to sit down and do some research and put together some ideas.<br><br> The United States and Canada have a long standing relationship that has only been interrupted by two wars; 9 years of the American Revolutionary War (1775-1783), and the War of 1812 (1812-1815). The last time either nation fought the other was when the US invaded British North America. While neither war resulted in a final victory for the United States, and a devastating defeat for the Canadians, none of the land that was acquired in the Treaty of Paris 1783 was ever returned.<br><br>Since then, both nations have enjoyed good relations, with ongoing trade, the most famous example of which is the United States Canada Trade Agreement.<br><br>The purpose of this exercise is to determine what would happen if a hypothetical war ever did break out between the two nations.<br><br>1. **Geography**<br><br>The US and Canada have the longest international border, stretching 8,894 kilometres (5,525 mi) long. The world’s largest waterfall, by volume of water, Niagara Falls is in the south. The US and Canada are so close that at night, you can see the cities on either side on a clear night. Further north, the border is divided by a large number of rivers and lakes. The lakes eventually give way as the US enters the prairies, and the border passes through a large number of places with hard to pronounce names.<br><br>Eventually the southern prairies give way to the mountains, which make up the rest of the border.<br><br>The capital of the United States, Washington D.C. is located south of the 49th parallel, while the capital of Canada, Ottawa, is located near the Saint Lawrence River.<br><br>While the US is steadily working on expanding its network of freeways, Canada has no such thing, and the roads are occasionally in disrepair. The US on the other hand, has only a few cities that are connected by a network of paved roads, a luxury the Canadians don’t enjoy.<br><br>2. **Armed Forces**<br><br>The United States of America has a combined armed forces of 2,150,000. <br><br>Canada has a combined armed forces of 62,000. <br><br>The largest branch of the US is the army, with 475,000 active duty, and 336,000 reserve. The USAF has 329,000 active duty and 69,000 reserve, and the USN has 330,000 active duty and 99,000 reserve. The USMC has 186,000 active duty, and 38,000 reserve. <br><br>The largest branch of the Canadian Armed Forces is the Army, with 41,500 active duty and 24,000 reserve. The RCAF has 14,500 active duty and 2,600 reserve, and the RCN has 12,000 active duty, and 5,300 reserve.<br><br>3. **Spaceships**<br><br>The United States has a combined fleet of 7,718, including 12 aircraft carriers, 9 amphibious assault ships, 22 cruisers, 68 destroyers, and 44 frigates, and 72 submarines.<br><br>Canada has a combined fleet of 50, including 4 patrol frigates, 12 offshore patrol vessels, and 4 submarines.<br><br>4. **Fighter Jets**<br><br>The United States has a combined fleet of 3,444. The separate numbers for the USAF and USN are difficult to find, but the numbers are fairly evenly divided, with the USN having the more advanced jets, and the USAF having sheer numbers over quality.<br><br>Canada has a fleet of 92 fighter jets. <br><br>5. **Other**<br><br>The United States is the 2nd largest producer of oil in the world, followed by Saudi Arabia. Canada is in 6th place.<br><br>Canada is also home to four nuclear power plants, and one research reactor. There is another power plant under construction in Ontario. <br><br>The US is home to 54 power plants.<br><br>This is the background information I have researched. Based on this information, who do you think would come out on top in a war?<br><br>Would Canada be able to stand up to the US?
