Fox News contributor Mike Pompeo joined 'America's Newsroom' to discuss the Biden admin's handling of heightening tension with Iran following a deadly strike in Jordan that killed three U.S. service members.

Iran has crossed the rubicon, when its proxies launched a drone attack that killed three of our soldiers in Jordan on Sunday. The strike marks a clear escalation in the de facto war launched by Iran on the United States, in response to the Oct. 7 terrorist attacks by Tehran-backed Hamas on Israel.

Iran will almost certainly ratchet up hostilities in the coming days, weeks and probably months. The window of opportunity for President Biden to tame Iran with decisive action is closing rapidly. Here’s why.

First, Tehran highly likely views the Biden administration as extremely risk-averse and unlikely to engage with it in a direct large-scale kinetic confrontation. Despite the steady escalation of the scope and scale of Tehran-backed attacks on U.S. forces and bases in the Middle East in the past 100 days, Washington’s response has been focused on proportionality and escalation control. Rather than establishing escalation dominance by bringing war home to Iran, the White House authorized only periodic individual strikes on proxy targets.

TIME FOR PRESIDENT BIDEN TO FOLLOW 'THE GIPPER' AND INVOKE THE REAGAN DOCTRINE AGAINST IRAN

The number of attacks by Iranian militias targeting U.S. military personnel from Oct. 17 to Jan. 29 has reached 165 and the number of injured Americans has climbed to 34, most involving traumatic brain damage. And yet, the key message coming out of the administration has been "We do not seek war with Iran."

Everyone, from Secretary........
