Well The United States is histories most successful country in virtually every regard with the exception of outsider public perception. lets think of this as if USA just collapsed over-night...
1.) The Middle East would break out into a massive war without the looming super-giant shadow that the States cast on the region, this war would include Russia, Israel, Iran, Pakistan, Afghanistan, and China...the major fronts would be the areas surrounding Iraq/Iran and the border between Russia and China.
2.) Britain, Spain, and France would lead a campaign to form the new United States, the first true United States of Europe, and along with Japan the new USE would split claim over the former USA landmass - Collapse of the USA would also spell the collapse of Canada, that land would also be up for grabs.
3.) Fearing a Chinese invasion of their homeland and newly gained territory of the US/Canada West Coast- again because of the absence of American influence - Japan would prepare to enter the great eastern war - siding with Russia an its allies for protection.
Russia would claim Alaska and much of the northern Half of Canada due to its close proximity. This would create tension within the USE due to being surrounded by the Russian/Japanese alliance forces to the north and west, already facing turmoil within from much of the eastern European countries who have not yet been absorbed by the USE - the USE would elect to stay out of the Russian and Japanese affairs, choosing instead to reactivate and strengthen the old USA airfields in Northern Maine - the most strategic launching ground for defensive and retaliatory bombing in case of far eastern attacks.
It would certain spell the story of a Third World War if the USA just failed dramatically overnight, you cannot underestimate the power and influence of the USA - it is far more powerful than many people think, simply because of the caution in instills on other militant forces around the world.
...uhh...ill just put my favorite quote of all time here.
"Welcome to Pain, the second of three...You have dealt the first...now deal with me!!"
