Oh before Pearl Harbor its pretty well documented. The 'Bund' held a rally at Madison Square Garden in 1940 or 1941 advocating Nazism as up and coming political party in America. After PH however they went off the radar and if they tried a rally like that during WW2 I have no doubt they would have been arrested.
Not saying that there isn't documentation but I doubt that any of it is addresses in grade or high school, let alone on the History Channel or PBS every year.
Also, with regards to the current "war". The war in Iraq is over. We do not fight Iraqis, we fight foreign terrorists who flood into Iraq. We are partnered with the Iraqis in this fight.
We fight a larger war on terrorism. Consider it like our fight with the Barbary pirates when Europe was paying them protection money.
The enemy has no government. Has no flag. Has no nation. Has no uniform. They have an ideology (Islam is a political system as well as it is a religious belief) and a belief, as did the Nazis and the WWII Shinto Japanese, that they world is their's.
Are we to treat the enemy as soldiers, troops we can kill before they fire upon us; as criminals due all legal rights of an American citizen; or rogues with no protections of the Genova conventions (since they are not signers to the agreement and have made it clear they do not abide by those rules)?
Clinton said that we should treat them as criminals and run them through our courts (see the 1993 WTC bombing; also see his policy of only accepting Bin Laden if he had something to charge him with).
Do we have agents who are "licensed to kill"? I'm not talking about Robertson's talk of a hit squad to take out Chavez. He is a head of state. I'm talking about rouge organizations that threaten security. Can we "whack" a spy or terrorist or not?
If the enemy are just "criminals" then we cannot fire on them until they shoot first. Regardless of the battlefield.
This is another cold war that will last a long (or very long) time.
It did not take killing every Japanese or Nazi to put an end to their world conquest or threats to society. It won't take that to defang Islamnazism either.
Not only arrested but they would have been beaten to a pulp and shunned by the people of the United States.
The 60's afforded a class of people the "right" to be unpatriotic and not face retribution (Carter's pardon of the run to Canada crowd).
Political correctness has run amok so that any criticism of motives is a personal attack.
