Really. Bush should have bombed the Iranian nukes, as Cheney seems to have advocated, and worked to undermine a barbaric regime that's committed many acts of war against the US. Instead Bush's good nature told him to leave that decision to the next President, realizing the problem of inheriting a direct conflict with Iran. But a more cold-blooded thinker would have taken Obama at his and his associates' word and presumed that Obama would betray Israel. And so it came to pass. Blame Bush and blame the Jews who voted for Obama.
The road to hell is paved with good intentions.
