McCain's speech had some good and reasoned points. I don'r agree with his position on Iraq- I feel the US-UK continued presence will prolong the conflict. Al-Qaida is active in Pakistan and other countries, as an ally for radical Islamists, and must be fought internationaly. Perhaps a united effort by the UN would be the best approach.

Whether withdrawal will spell the beginning of a bloodbath, I am not sure it will. I believe that saner heads in both Syria (support for Sunni) and Iran (support for Shia) will prevail to prevent an all out confrontation, which would further the interests of neither country.

Youtube is not a place from which to judge the campaign adversaries. It sells 'the flavor of the day,' to use the cliché.
Like the speech by McCain, posted by McGrath, there have been speeches by Clinton, but they are under-reported.
