The problem is that progressives, and the Democratic party in particular, have lacked, or have been unable to articulate, a sound foreign policy that ordinary Americans are comfortable. For this reason, they get caught voting for the IWR and funding legislation because they have nothing to offer in place of muscle-flexing foreign policy:
"The current debate on financing military operations in Iraq, as well as the Memorial Day just past, stimulated yet again my 30-year search for a national security policy that liberal and progressive Americans can endorse.
...
Absent a new understanding of security and identification with achieving it, Democratic progressives will continue to be seen as anti-military and therefore anti-security. Consequently, when the nation feels itself to be endangered, it will always turn to conservative leaders. This cycle must be broken."

The American Security Project:
"Letter from The Honorable Gary Hart
The American Security Project has been created to develop a national security vision and strategy for the twenty-first century, building on America’s strengths, restoring its international leadership, and seeking solutions to the new realities of the 21st century before they become crises.
American national security policy is adrift. In the five years since the attacks of 9/11, the United States has toppled autocratic regimes, cast-aside collective security alliances, put its military into the field, expanded its covert battle against terrorists, and simultaneously lost its moral standing in much of the world. While American activism has not always met with approval in the international community, there once was a time when American action made us stronger. Today, however, anti-Americanism is fueled by actions that are seen as diversions from America’s historic path, accepted standards of international behavior, and common sense.
The issue at hand is the appropriate purpose and use of American power. Where the United States has needed strategy, we have been offered tactics. There has been little development of grand strategic thought since the end of the Cold War.
The so-called “war on terror” has dominated every discussion of national security since September 11, 2001. But the war-paradigm—while convenient for political mobilization—is dangerously imprecise and counterproductive in the fight against extremists. The American Security Project seeks to clarify the nature of the struggle the United States faces against violent-extremists in order to produce more effective policies and strategies to meet the threat."
http://www.americansecurityproject.org/aboutHart is again working with former New Hampshire Senator Warren Rudman, whom he co-chaired the Hart-Rudman commission which presciently predicted the terrorist attacks on 9-11.
American foreign policy should be bi-partisan, not "my way or the highway".
Partisanship should end at the water's edge.
