Washington (CNN) – A leading Republican strategist and one-time aide to former Vice President Cheney said Sunday that President Obama’s recently announced decision to send an additional 30, 000 troops to Afghanistan is “a reassertion of the Bush doctrine.”

“The [Bush] doctrine is no safe havens [for terrorists intent on harming the United States] and we go after those that provide a harbor [for such terrorists]. That’s the doctrine,” Republican strategist Mary Matalin explained Sunday on CNN’s State of the Union.

Obama’s decision to surge additional troops into Afghanistan is “solid policy,’ in Matalin’s view and “a reassertion of the Bush doctrine.”

“Every strategic element is from the Bush doctrine. The tactics are from the Bush surge [in Iraq],” she said.

Matalin added that when civilian contractors and forces supplied by NATO allies are considered “there are enough troops” in Afghanistan.

But, Matalin also said Sunday that, by announcing a date to begin to remove some American troops, Obama had sent a mixed message about the United States’ commitment in Afghanistan.
