Yes, Obama wants to end the Iraq War but, the 2008 Democratic Party platform flatly states:
Expand the Armed Forces
We support plans to increase the size of the Army by 65,000 troops and the Marines by 27,000 troops. Increasing our end strength will help units retrain and re-equip properly between deployments and decrease the strain on military families. 3
Recruit and Retain
A nation of 300 million people should not struggle to find additional qualified personnel to serve.
Recruitment and retention problems have been swept under the rug, including by applying inconsistent standards and using the "Stop Loss" program to keep our servicemen and women
in the force after their enlistment has expired. We will reach out to youth, as well as to the parents, teachers, coaches, and community and religious leaders who influence them, (emphasis mine) and make it an imperative to restore the ethic of public service, whether it be serving their local communities in such roles as teachers or first responders, or serving in the military and reserve forces (emphasis mine)or diplomatic corps that keep our nation free and safe. 4
Re-train and re-equip properly between deployments? Sounds like Obama plans to keep the military busy.
This indicates that Obama will only provide a change of tactics, not strategy. The Iraq War is bad, but war itself is a perfectly permissible tool of foreign policy. Rep. Ron Paul, who sought the Republican nomination himself this year, understands the issue. In an interview with CNN's Kiran Chetry in August, he stated that there was no difference between the foreign policies of Sens. McCain and Obama:
"Their foreign policies are identical," Paul explained. "They want more troops in Afghanistan. They want to send more support to Georgia to protect the oil line there. Neither one says bring home the troops from Iraq from the bases -- you know the bases are going to stay there, the embassy as big as the Vatican, that's going to remain. So their foreign policies are exactly the same. They're both very, very aggressive with Iran. So I would say there's no difference."
