without a kick ass military there would be no quality of life in this country. I do agree that we should not be the world's police force or telling other countries how to live.
LOL
Of course there would There isn't a nation on earth capable of invading us. We haven't been invaded in 200 years
What exactly do you call 9/11?
A terrorist attack. An "invasion" is when troops from a foreign country land on US soil, and proceed to "invade" the country. The last time it happened, was the War of 1812, when British soldiers burned down the White House.
Similarly, Pearl Harbour, while a terrible event in US history with great loss of life, was also NOT an invasion. No Japanese troops landed on US soil. Pearl Harbour was an "attack", not an invasion.
It doesn't change the horror of the events or the loss of life and devastation caused in these attacks, but they were not invasions.
