I think I understand these practical difficulties pretty well.
I also understand that if we let the Left sectarians have their way, we will always play by the same script:
Rally -> March -> Rally -> Go home
At least there are some encouraging developments among the anti-war elements. Some folks are engaging in more militant tactics. Lots of folks are doing educational events. There are lots of local, independent action popping up all over.
You talk about storming air bases. We all understand that those are well fortified. So, what are the other chokepoints for the U.S. war machine? If you were going to interfere with the "just in time" aspect of the current war effort, where would you put pressure? How about the propaganda machine? The CNN offices aren't fortified. How about the PR machine? The offices of the Ad Council and the Rendon Group aren't fortified either.
Let's think outside of the box.
Do you know how the people in the Phillipines brought down that corrupt government? Cell phone and beeper agitprop.
Writers on the Left have written some great stuff against the war. How many of us have forwarded those articles to the "CC" lists that always come appended with bad Internet jokes? Articles by Left writers are so frequently passed around between the usual suspects. What would happen if each of made an attempt to get these articles and essays out to average working people via email.
Net Anti-War to defeat the War.
