Robert Menendez actually said...

We have lost the opportunity and emboldened and strengthened our enemies whether those are Assad, Iran, Russia, the Islamic State.

The degree of carnage and butchery is unparalleled today, and it has bled over into Europe in a trail of death.

This policy option is infeasible for the United States, from moral, political, and security standpoints.

The Russians cannot bomb their way to peace. The Iranians cannot prop up Assad forever.
