edit - the post I was replying to has been deleted... Interesting. Here's my response anyhow.
If you're implying that the US is "occupying" Iraq, you're sadly mistaken. The Iraqi people never gave up... They merely tolerated the US presence. The war was over too fast for the population to feel that they were defeated. We showed up one day, blew the crap out of anyone who shot back, tore down some statues, and asked people to keep doing what they used to do the week before.
For the majority of Iraqis, at worst we're unwelcome guests tracking muddy bootprints around the country who are providing an excuse for various religious whackos to kidnap, torture, and blow up each other. They know darn well that if we left now, a religious "civil war" would break out overnight.
We don't have anywhere near the number of troops anywhere to "occupy" any other country. If the Iraqis really wanted us out, it would take maybe a week before we were on the run.
If you're talking about Israel, again you're completely exaggerating. If a Mexican terrorist group backed by Cuba was tossing rockets into San Diego, you bet your butt we'd roll in and do the exact same thing Israel is currently doing. The arguments are the same, except that the Mexicans aren't violent or crazy enough to try to retake Texas by force. They're going to move in and outbreed us instead. But if someone backed by Cuba did try rockets and blowing up busses in SoCal, Arizona, and TX, we'd push the border back in a hurry and probably take Cuba just to show we were serious.
So... what occupational armies ARE you talking about?
