"Israeli PM demands Obama commit to military action if Iran sanctions fail"?

The above was the heading to an article in yesterday's (March 1) Guardian, a respectable British paper. It has been clear for a long time that Israel is pushing US into a war with Iran, like they did in Iraq. Why is the American government so servile to Israel, why does it betray Americans and the world in general to cater to Israeli and Zionist interests? Why do they give at least $3 billion a year to Israel and end up being bought by Israeli lobbies such as AIPAC? Why have they allowed the mainstream US media be controlled by the Zionists when it is a truism that for democracy to function it is essential to have a healthy and balanced media? Why are so many strategic administrative positions held by advocates of Israeli interests instead of American people's interests? Can this situation be explained?
