seemed to have missed the point buddy. middle eastern muslim terrorists actively attempt to attack the united states. despite being closer and easier, they do not attack portugal, holland, belgium, italy, etc, etc, all free democracies. they do not attempt to attack japan. they attempt to attack the united states, because we prop up israel (and more recently our invasions and occupations). those who were allies in our recent invasion of iraq, were also attacked (britain and spain). as soon as spain withdrew their troops, middle eastern muslims stopped trying to attack them. southeastern asian muslim groups, while being a thorn in the side of their own nations, dont try to kill blow up buildings or kill people in the united states 
You're missing the point buddy. Holland, Belgium and these other countries have arrested countless suspected terrorists over the last few years. Just because they haven't succeeded in attacking them doesn't mean they're not trying to. Have you read anything anyone has said to you? Obviously you haven't.
Japan hasn't been attacked because like youandme said, Muslims are watched like Hawks. It's damn near impossible to get a gun into Japan, let alone hundreds of pounds of explosives, plan an attack, and carry it out.
What were those Muslims of Middle Eastern descent doing in Britain last year when they loaded that Mercedes with gasoline canisters and ball bearings and tried to blow it up outside a night club? Celebrating a birthday? Or when they drove that car into Heathrow and tried to blow it up after the car failed to detonate?
Spain wasn't attacked by middle eastern Muslims? LOL. The Madrid train bombings were carried out by Middle Eastern Muslims who were inspired by Al Qaeda's principles. Do some reading before you try to pull fallacies out of thin air.
By the way , the southeastern Asian groups don't attack the American homefront because they can't get to it. They just blow up night clubs in Bali that are full of foreigners. The 2002 Bali club bombings ring a bell? Jemaah Islamiyah is notorious for targeting Americans and foreigners.
Anyone who thinks terrorism will just up and vanish if the US stops supporting Israel is a god damn moron. Plain and simple.
You've just done a good job proving that you have absolutely zero grasp of anything regarding this topic. Some people are so obtuse it's astounding.
