Put your money where your mouth is

Donate money to an Iraqi relief organization.
If you opposed the war on humanitarian grounds, I challenge you to donate at least $10. If every American who marched protesting the war donated $10, they'd raise $50 million.

Here's a short list of reputable relief organizations:

» Mercy Corps
» Red Cross and Red Crescent
» Doctors Without Borders
» Catholic Relief Services

And of course there's always UNICEF.

Though humanitarian aid takes precedence, it's important to support organizations promoting democracy. Such as The Foundation for the Defense of Democracies and The Iraq Foundation.
