Personally, I'm not so sanguine. This administration and this crop of congressional 'leaders' rolled out the red carpet for Abu Mazen, the financier of the 1972 Munich Massacre.
Why is Hamas any different?
Unprincipled 'diplomats' will be trying to make them into statesmen by the morrow...
The Palestinians have always been determined to destroy Israel. The only difference between Fatah and Hamas is that Fatah wants to first weaken Israel's position as much as possible via negotiated victories before they turn to force of arms, and Hamas wants to just get on with it now.
