Bonus: the story was written by Geoff Johns, well before he became DC's savior/superstar. The issue has no dismemberment, no characters skinned alive or vomiting blood. Remember those days, Geoff, when you could write great stories based on the characters, and not have to rely on hyper-violence and gore for shock value? Seriously, his Avengers run was pretty good...
Since we're now less than three weeks away from the debut of the new Captain America, I figure that this a good opportunity to present my favorite Captain America moment EVER.
Setting the scene: 2003 (our time). In the Eastern European nation of Slokovia, a movement worshipping Thor and Asgard has taken hold among the populace. The ruling junta doesn't like this, and targets the Thor followers for genocide. They pray to Thor for help, and he brings down the host of Asgard.
To counter, the junta buys a lot of advanced weaponry from Dr. Doom (Protip: don't do this, small countries). All the surrounding countries are getting nervous, as are the US and Russia. Doom is using his ability to remotely control the weapons to ratchet up the situation. The Pentagon sends Iron Man in to intercede with Thor, but America has troops massed at the border in case that fails. Russia has bombers in the air, with orders to blow up everybody if the US gets involved. World War III is imminent, as Doom chuckles. And it's all up to Cap to prevent it:
Ladies and gentleman, that is Captain Freakin' America.
Geoff Johns and Alan Davis show us who wears the pants in the U.S. military in Avengers #63 (or 478, whatever floats your boat), 2003.
