I've had a look on Google Earth, and the only way a missile going from Iran to the USA would pass over Poland (assuming it travels in a straight line, taking the shortest possible route according to Google Earth's algorithms) is if the missile was fired from the west side of Iran and aimed at the east coast of the USA. Again assuming that any missiles fired from Iran to the USA are going in the shortest straight line possible, I would say that anti missile defences would be more useful in Canada, or even the USA itself, although then any missiles aimed at targets in the north wouldn't be intercepted. Even better than Canada, on the other hand, would be Russia, which is directly between Iran and the USA. Although American missile defences in Russia itself may not go down too well...

Even if it is targeted towards Russia, so what? You must be living on another world if you do not believe that Russia is still a threat. They are bitter about the break of the Soviet Union and the power they once held. They do not shy from using their oil reserves to regain that power. It is in Poland's interest to have this shield. It is defensive in nature and the only thing Russia should fear is that they will not be able to nuke Poland. Where is the problem? Polish American from Chicago

This is a No-Brainer. Putin is going to start an arms race regarless of the missile shield or not.

Poland is right this time, the new American missiles are actually aimed against Russia and not Iran, Iran is juts an excuse for the Americans to put the missiles in Poland.
There is no threat now, tomorrow, or ever, from Iran, but there is a real and imminent threat, and that threat comes from Israel which has atomic weapons and they are ready to strike any country in Europe.
Yes, Israel is a threat to the world peace. If the U.S wants to protect Europe and Russia too from nuclear attacks, the U.S must put their anti-missile shield in Albania, or in Kosova , facing Israel where the real threat to the security of Europe comes. from.
.
Iran has no quarrels with Russia or with Europe, it has only with Israel because Israel is armed with atomic weapons which are aimed against Iran and the Iranian people,.
