Middle East historian and blogger Juan Cole recently wrote a polemic against progressive U.S. critics of the new U.S. war in Libya. In his polemic, he wrote, "I hope we can have a calm and civilized discussion of the rights and wrongs here."
I strongly agree with Juan that it is important for progressive critics of U.S. foreign policy to try to have a calm and civilized discussion about the issues that have been raised by the U.S. military intervention in Libya. In general, it's important to try to have calm and civilized discussions about all issues of public policy, even when - especially when - the underlying issues are matters of life and death. The alternative is nasty polemics, and a principal effect of nasty polemics is to exclude people from discussion who don't want to engage in nasty polemics. In this way the effect of nasty polemics is anti-democratic; nasty polemics tend to demobilize people and cause them to disengage, when what we need is the opposite: more engagement and more mobilization.
In this particular case, the decision of the Obama Administration to engage the country in a new Middle East war without Congressional authorization represents a long-term threat to the U.S. peace movement, because the U.S. peace movement is engaged in a long struggle to try to influence U.S. policy in the direction of less war, and Congress is a key arena in which the peace movement tries to assert influence over U.S. policy. If you take away power from Congress to determine issues of war and peace, you substantially reduce the power of the U.S. peace movement to influence issues of war and peace. Taking away Congressional war powers is to the peace movement like taking away collective bargaining is to the labor movement: a direct threat to our ability to move our agenda on behalf of our constituents.
