Biden Draws ‘red Line’ For Benjamin Netanyahu

President Barack Obama infamously declared that the use of chemical weapons by Syrian dictator Bashar Assad’s regime constituted a “red line” that would spark a direct U.S. military response. Mr. Biden was vice president at the time.

A year later after Mr. Obama’s warning, Mr. Assad used chemical weapons against his enemies, but the U.S. did not strike. The Obama administration later cut a deal in which Syria would turn over all of its chemical weapons to Russia, though by virtually all accounts, Mr. Assad retained some chemical weapons capability.
