Iraq does pose a serious threat to the stability of the Persian Gulf and we should organize an international coalition to eliminate his access to weapons of mass destruction. Iraq's search for weapons of mass destruction has proven impossible to completely deter and we should assume that it will continue for as long as Saddam is in power.

We're putting 70 million tonnes of pollution into the atmosphere every day, trapping an enormous amount of extra heat from the sun inside the earth's atmosphere. It's threatening to push the planet past a tipping point beyond which climate change would be difficult to stop
