The US Senate will begin debating today on a resolution that would grant US President George Bush the authority to use military force against Iraq. Yesterday, a bi-partisan House delegation joined Bush in the White House Rose Garden after having supported a similar resolution. The proposal is open to various interpretations, however. Some Republicans say it gives the President the power to launch a strike on Baghdad without the support of the United Nations Security Council. Some Democrats, however, say that Bush must exhaust all UN avenues before using the force.
