Instead, almost everyone seems up for dither and defer at the moment.
A look at how the past days' parallel tracks - pushing for approval of a military attack while pausing to give diplomacy a chance - unfolded:
Obama pressed his case with world leaders at the Group of 20 summit, which included an opulent dinner last Thursday night (local time) with ballet dancers and fire jugglers. His pitch slipped past midnight on a night capped by St. Petersburg fireworks at 2am. After Friday's round of meetings, the burden of a looming military strike in retaliation for Syrian chemical weapons use and the lack of explicit support from summit partners weighed visibly on the president when he addressed the traveling press corps. It's conceivable that "I don't persuade a majority of the American people that it's the right thing to do," he said. "And then each member of Congress is going to have to decide."
And then he would have to decide whether to attack Syria, even absent congressional support.
With plenty of US-Russian tensions simmering - over Syria, Moscow's sheltering of former NSA leaker Edward Snowden and more - Obama decided there would be no formal one-on-one with Putin. But the Russian leader, the Syrian government's leading patron on the world stage, approached him Friday and they pulled chairs together off to the side.
Flanked only by interpreters, with other leaders looking on, they launched into a 20-minute discussion about Syria. There was no breakthrough on one vexing aspect of their disagreement - the future of Syrian President Bashar Assad. However, Putin broached an idea that the two leaders had first discussed a year ago at the G20 summit in Mexico - an international agreement to secure Syria's chemical weapons stockpiles.
Obama agreed that could be an area for cooperation and suggested Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov follow up. You wouldn't know it from Obama's public mood that day, but seeds had been planted.
Since August 23, administration officials have had discussions about Syria with more than 370 House members and nearly all senators, according to the White House count. The pace picked up on the weekend and into Monday, as members of Congress returned from a summer break that had kept many of them engaged on Syria only from afar. They'd already, though, gotten an earful from constituents against military action.
Back in Washington lawmakers were shown a collection of videos, also released publicly, showing victims of the August 21 chemical attacks that the US blames on Assad's forces. There were repeated presentations of those videos, to bring home the brutality of gassing, although they did not prove who was responsible.
"I cannot look at those pictures - those little children laying on the ground, their eyes glassy, their bodies twitching - and not think of my own two kids," said Susan Rice, Obama's national security adviser, as part of the lobbying offensive.
Obama and Vice President Joe Biden pressed members of Congress at a dinner Sunday night as well as in a battery of phone calls over days. Lawmakers walked swiftly from one briefing to the next Monday and gathered en masse in the large Capitol Visitors Center auditorium for a session with top national security officials.
Nothing seemed to be working. More and more lawmakers stepped forward to declare their opposition to military strikes. The dynamics - for and against military action - were strikingly bipartisan.
But those seeds from the palace were taking root.
On Monday morning (local time), Kerry, in London, held a news conference with British Foreign Secretary William Hague, greeted outside by 50 protesters chanting, "Keep your hands off Syria."
"I think it would be good to hear people saying to a dictator, 'Keep your hands off chemical weapons that kill your own people,'" Kerry retorted inside the room.
Since early in the crisis, and until Obama stepped up, Kerry had been the main figure pitching the Syrian strategy. To lawmakers, in speeches and at news conferences, he spoke passionately and sometimes misspoke. At one point, he even seemed to hold out a last-resort option of ground troops in Syria, in the face of numbingly repetitive assurances by US officials of no-boots-on-the-ground. This time, he swerved verbally in the other direction, stating US action against Syria would be "unbelievably small," raising questions about why bother.
When Kerry was asked if Assad could do anything to avoid an attack, he uttered 20 words that set off a rapid chain of events.
"Sure," he said. "He can turn over every single bit of his chemical weapons to the international community in the next week."
He raised both arms for emphasis and continued: "Turn it over, all of it, without delay, and allow a full and total accounting for that. But he isn't about to do it, and it can't be done, obviously."
On the flight home, Kerry, now in a faded orange zip-up sweatshirt, spoke on the phone with Lavrov, the Russian foreign minister. Lavrov told Kerry he had heard his comments in London and Russia was getting ready to make an announcement.
By the time Kerry landed in the US, Russia had made its proposal to place Syrian chemical weapons out of Assad's control, Syria had welcomed the idea, other nations and the United Nations had embraced it in principle, and some members of Congress were beginning to see a possible way out of the jam. Kerry's staff initially suggested that the secretary's words were merely a rhetorical flourish. But by the end of the day, though expressing deep scepticism, Obama declared the Russian pitch "potentially a significant breakthrough" that could head off US air strikes.
Some members of Congress were beside themselves, trying to make sense of it all. First the Obama administration had appeared to be marching toward a strike. Then the president hit pause and asked Congress to approve his course. Then came the Russian idea, so yet another pause. Altogether, the arguments of the administration had grown awfully complicated and seemed to be changing by the hour.
"I'm going to start looking for medication," Rep. Howard "Buck" McKeon, R-Calif., chairman of the House Armed Services Committee., remarked Tuesday morning. "This place is a zoo."
Obama's address to the nation yesterday afternoon (NZT) wasn't the trumpet call to action that it might have been, absent the diplomatic initiative on Syrian chemical weapons. His statement reflected the complexities of the moment - a chance to avoid war, as he saw it, but a continuing need for congressional approval to keep a credible military threat alive.
Until recently, the Senate had been expected to conduct an initial vote Wednesday, beginning an arduous legislative process to be echoed in coming days in the House, where opposition to a military strike has been an even tougher sell.
Instead it was dither and defer, at least for a while longer, with everyone treading carefully. Any resolution on Syria was on hold on Capitol Hill.
"The whole terrain has changed," Sen. Dick Durbin, D-Ill., said after a meeting of Democrats on the Senate Foreign Relations Committee. "We want to make sure we do nothing that's going to derail what's going on."
