What about US?

Condi, still working despite it being vacation season, went to Poland for the signing of the anti-RussianIranian anti-missile missile treaty. The US had been holding out over Polish demands that the US agree to defend Poland on a front-line basis, beyond its obligations through NATO. The Georgia war was enough to override any second thoughts the US might have had.

The Czechs are also part of the deal, since they will be hosting the radar stations that will make the whole thing work.

The deals, though, are not yet really finalized:

The agreements with Poland and the Czech Republic, both members of NATO, must still be ratified by their Parliaments.

Well and good. But why doesn't the US need to get the Senate to sign off on a treaty that obligates the US to defend another nation outside NATO? It's not like there would be any problems getting the Democrats to line up once again and swear fealty to Feckless Leader. I guess he wanted to show that he didn't need no stinkin' Senate ratification. But is an executive agreement binding on the next executive? Beware, Poland!
