Hillary Rodham Clinton -- former first lady, presidential contender, and now secretary of state -- knows painfully first-hand how difficult a lift health care is.

So she counsels patience as Congress and the White House tries to come up with a bill that can pass -- and that can work.

"I'm very encouraged by the action that's going on in the Senate. But I think I, probably better than anyone, know how difficult this is," she said in an interview aired on CNN today.

"But we've made a lot of progress in the last nine months. And I'm very optimistic we're going to get a health care plan that will really improve the lives of the American people," added Clinton, who led a White House health care task force in 1993-94 that submitted a detailed bill to Congress that was derided as "Hillarycare" and went nowhere.

In the interview, Clinton also preached patience on Obama's decision whether to dispatch more US troops to Afghanistan, saying that "it's to the president's credit that he has had the patience and the persistence to really force the process without responding prematurely."

The president, she said, needs to closely scrutinize the broad view of what the US mission in Afghanistan should be and how best to accomplish it, citing a recent strategic review.

"It was quite remarkable that the report came in with two big ideas that had not, in my view, been fully either explored or certainly implemented in the prior eight years," she said. "One was you've got to look at Afghanistan and Pakistan together. Now, that may sound self-evident. But that wasn't what was being done previously. And you have to have a much greater integration of the civilian and the military efforts."
