I really would appreciate it if someone would answer my question:

Suppose a radical group in Canada continuously fires rockets at major United States cities, attacks United States citizens and kidnaps United States soldiers while the Canadian government stands by and does absolutely nothing to remedy the situation (They claim they're too weak to effectively deal with the radicals). Let's also suppose that this radical group has some amount of political say-so in Canada. How long do you think it would take the United States to take matters into it's own hands and, given the circumtances, would anyone blame the United States for invading Canada to remove the threat posed to the United States?

A country has to protect it's borders and, more imporantly, it's citizens.
