Syria / the timeline has been established

The administration is planning to release evidence, possibly as soon as Thursday, that it will say proves that Syrian President Bashar al-Assad bears responsibility for what U.S. officials have called an “undeniable” chemical attack that killed hundreds on the outskirts of the Syrian capital

The timing of such a military response is being dictated by the need not only to assemble incontrovertible evidence against Assad — an important prerequisite for the administration, and the country, given the recent memories of a war based on false claims of weapons of mass destruction — but also to allow consultation with Congress and international partners.
