(CNN) - Georgia Rep. Tom Price, just back from Afghanistan, told CNN Monday that President Obama must sound resolute about his commitment to winning the war in Afghanistan when he unveils his military strategy for the country Tuesday evening.
"If he says that he's going to commit 32,000 or 34,000 more troops and maybe it will work or maybe it won't, that's not the message we need to hear or the world needs to hear," said Price, a Republican who spent the Thanksgiving holiday in Afghanistan. "What the world needs to hear is he's going to commit the number of troops necessary and accomplish the task and mission of keeping the American people safe. That's the most important thing."
Ultimately, Price said, success in Afghanistan could come down to the tone of the president's message when he announces his Afghanistan plan in a highly-anticipated speech at the U.S. Military Academy at West Point.
"If he talks about an exit strategy only and if he talks about benchmarks in terms of calendar time lines, that's where the challenge is because the Afghan people are hedging their bets," Price said. "They are not certain America is committed to prevailing in this mission. If the president is very resolute and very specific about what he believes the mission is and what can be accomplished, I think we'll be fine."
In the speech, Obama will explain why the United States is in Afghanistan, its interests there, and his decision-making process, White House Press Secretary Robert Gibbs said last week, adding that the president "does not see this as an open-ended engagement."
"Our time there will be limited, and I think that's important for people to understand," Gibbs said.
