That said, Hagel reiterated that the Obama administration is "committed to working with the international community" regarding any possible military action taken in Syria.
“We have moved assets in place to be able to fulfill and comply with whatever option the president wishes to take,” Hagel said during a press briefing in Brunei on Tuesday.
Four Arleigh Burke-class destroyers, armed with long-range Tomahawk cruise missiles, are on station in the Mediterranean, awaiting further ordered from Washington.

The proposed three days of strikes inside Syria could begin as early as Thursday, according to NBC News.
U.S. officials told NBC the strikes would be limited in scope, and are not designed to help rebel forces in the country overthrow embattled President Bashar Assad.

Administration officials said over the weekend they have “little doubt” that Assad's forces used poison gas.
According to opposition groups, the death toll from the attack stands at more than 1,000.
Use of those weapons crosses "red line" set by the Obama administration, which would trigger a U.S. military response.
American and allied officials strongly condemned the Assad regime's reported use of chemical weapons in a series of statements issued in recent days.

On Tuesday, French President François Hollande said France is “ready to punish” those behind the “chemical massacre” in Syria, according to recent reports.
France, the United Kingdom, Germany and Turkey have all recently issued public statements of support for any possible military action U.S. forces may take in Syria.
