How about something like:
We, the Democratic party, oppose all forms of terrorism and violence against civilian populations, and the terrible attacks on 9/11 helped remind us that terrorism is global in scope, and the fight against terrorism must equally be global in scope. We therefore support strong, international action to capture and kill terrorists and punish those regimes which support them.
However, we can not do this alone. Terrorism is a multinational problem, and only a multinational solution is possible. We need cooperation with the rest of the world to fight the war on terror. Therefore, the US must call upon our allies, both in NATO and around the world, and must open dialogue with every nation affected by terrorism, as well as work with the UN and existing multinational organizations to develop a worldwide and unified response against the terrorist threat.
The Democratic party also realizes that an effective way to combat terrorism is to act on the underlying reasons that individuals join terrorist movements. Therefore, the Democratic party is committed to encouraging democratic values and human rights around the world, so that individuals can find peaceful ways to protest, and also to increase aid to the poorest nations of the world and work to increase the standard of living worldwide. We will work with the IMF and World Bank to renegotiate the interest payments that trap so many third world nations into a cycle of crushing debt and economic crisis. We will work to encourage a fair peace and settlement in Israel and Palestine, in Northern Ireland, in Sri Lanka, in Cyprus, and everywhere around the world there is conflict.
The war against terrorism also must be fought at home. We therefore support tougher penalties against terrorist acts and funding of terrorism, and we will work to identify domestic organizations that fund and support terrorists and shut them down and prosecute them. We will step up our border security to make certain that people can not enter the US illegally and that those with evil intent can never cross our borders. However, we can not allow the fight against terrorism to take from Americans those civil rights which our ancestors have fought for. We must therefore make certain that those accused of supporting terrorism are represented by competant counsel, and are tried in an open and fair court. We must make certain that the rights of those investigated are respected.
The fight against terrorism will not be an easy one, nor one without cost. However, it is a fight we must fight, a fight we must win. And it is a fight we can win. Since its founding, the United States has never been afraid to fight, and under our leadership, we will defeat the terrorist threat and make both the US and the world safer.
