re: How successful would a country be invading the U.S.?

Haven't read the whole thread but if an enemy detonated a nuke over us creating an EMP that knocks out all or a significant portion of the power grids and anything else electrical....a large portion of the populace would kill each other quickly in food and water wars. Any military and police force would be dedicated to keeping any shred of government and order going.

Then that enemy could invade within a month and have an easier time. I don't know if it'd be successful but it's better than just herp derp invading. Of course they'd have to make it past our navy which would be no small feat.

In conclusion, it'd be pretty damn hard.
