The tough message Biden just sent Iran

In a single stroke on Thursday, President Joe Biden did far more than destroy a few support facilities for Iranian-backed Syrian militias. Unlike his two predecessors, Biden has drawn a new red line in the Middle East and shown he is prepared to defend it.
Pentagon officials said two F15s dropped Joint Direct Attack Munitions (precision weapons with GPS navigation capabilities) on buildings at an unofficial border crossing believed to be used by militias to transfer munitions into Syria from Iraq.
The strike sought to cripple the ability of these groups, particularly Kata'ib Hezbollah and Kata'ib Sayyid al Shuhada, to attack American forces, Pentagon spokesman John Kirby said.
