(NBC News) At nine o'clock eastern time tonight, President Obama addresses the American people and it's going to be a tough sell.
He wants the public and Congress to support military strikes on Syria.
But there's even more opposition to that since Syria now claims it would give up control of its chemical weapons.
At the White house, officials say secret talks between Russia and the U.S., some involving President Obama himself, led to this possible Syrian breakthrough.
But the President still wants the military option.
President Obama will argue tonight that the threat of U.S. military strikes is the reason Syria seems to be backing down.
Dictator Bashir al Assad agreeing to declare his chemical weapons and to never use such weapons and to turn over his stockpiles to Russia.
President Obama is hopeful.
"This could potentially be a significant breakthrough. But we have to be skeptical because this is not how we've seen them operate over the last couple a years," the President said.
And Russian President Putin said today the plan will only work if the U.S. rejects using force to keep the pressure on Syria and Russia the President had gone to Capitol Hill to personally ask lawmakers to authorize military strikes
But he's losing support.
"So i will be voting against this resolution. A vital national security risk is clearly not at play," said republican Senator Mitch McConnell of Kentucky.
58% of Americans want their member of Congress to say no to military action, in the new NBC News Wall St. journal poll.
And the Senate vote has been delayed.
Republican Congressman Jeff Miller of Florida questioned Secretary of State Kerry over whether Congress has the votes to strike Syria.
"Because they don't have votes, Mr. Secretary. That's why they delayed. You know that (Kerry) Actually i don't know that (Miller) Well I do."
As the Syrian-Russian plan goes to the United Nations, team Obama still wants an ok from Congress to strike.
"For this diplomatic option to have a chance of succeeding the credible real threat of U.S. military action must continue," said Defense Secretary Chuck Hagel.
The President will argue that tonight.
If he fails, If the polls don't move. If Congress votes no, If the Russian plan fails, President Obama says he has not decided if he will order strikes on Syria anyway.
