That sword cuts both ways! If politics stops at the waters edge, Obama did exactly what he accused GW of doing. He staged a political attack against a sitting President while he was out of the country.
GWs' speech did not name anyone as the "appeaser". But with Obama everything is always about ME, so if the shoe fits, wear it. I think it more likely that GW was making a veiled reference to Israeli PM Olmert and his tepid approach to his rather bellicose neighbors. I also think the Israeli Knesset gave him a hearty round of applause because they were smart enough to "catch his drift", even if the Obamanation didn't.

Actually, GWB was making a direct reference to Sen. William Borah (ID) -- a Republican.
But, as you point out, look who rose to the bait...
