In 2001, the administration of U.S. President George W. Bush expanded the program with the appropriation of $676 million for the Andean Counterdrug Initiative. Of this appropriation, approximately $380 million was targeted at Colombia. The rest went towards other South American countries covered by the Andean Counterdrug Initiative. The 2001 initiative reduced the limitations on the numbers and the activities of civilian contractors, allowing them to carry and use military weapons which, according to the U.S. government, would be necessary to ensure the safety of personnel and equipment during spray missions. The United States Congress rejected amendments to the Andean initiative that would have redirected some of the money to demand reduction programs in the United States, primarily through funding of drug treatment services. Some critics have opposed the rejection of these modifications, claiming that the drug problem and its multiple repercussions would be structurally addressed by curbing the demand, and not the production, of illicit drugs, since drug crops can always be regrown and transplanted elsewhere, inside or outside Colombia and its neighboring countries, as long as there is a commercially viable market.
In 2004, the United States appropriated approximately $727 million for the Andean Counterdrug Initiative, $463 million of which was targeted at Colombia.
In October 2004, the compromise version of two U.S. House-Senate bills was approved, increasing the number of U.S. military advisors that operate in the country as part of Plan Colombia to 800 (from 400) and that of private contractors to 600 (from 400).[35]
In a November 22, 2004 visit to Cartagena, President Bush stood by Colombian president Uribe's security policies and declared his support for continuing to provide Plan Colombia aid in the future. Bush claimed the initiative enjoys "wide bipartisan support" in the US and in the coming year he would ask Congress to renew its support
