Good on Putin. He must be heartily sick of Bush's lecturing and hypocrisy.
I doubt any air defense or any humanitarian or logical consideration for that matter will deter Bush and Blair going out in a blaze of glory. They are both tarred as liars and war mongers. Why not escalate? Nothing to lose.
Olmert is also a desparado. Israel might run another false flag operation to give an excuse for an attack on Iran. They did this to the minesweeper Liberty during the Suez war.
