About Secretary Esper

Dr. Mark T. Esper became the 27th Secretary of Defense in July 2019 when he was confirmed in an overwhelming 90-8 vote by the U.S. Senate in rare bipartisan fashion. Esper went on to successfully lead the Defense Department through an unprecedented time in the nation’s history: from conflict with Iran, an ongoing military campaign in Afghanistan, and counter-terrorist operations in the Middle East; to open competition with China and Russia amidst a fundamental shift in the geo-strategic environment; and from the greatest civil unrest and political turmoil America has seen in decades, to a major recession and the spread of a global pandemic the world had not experienced in over 100 years, all while dealing with an unpredictable White House.

Collapse of the Assad Regime

December 8, 2024
The collapse of the brutal Assad regime may not be the last domino to fall in this region. Iran is now the weakest it’s been in decades with the apparent loss of its Syrian client state; the collapse of its Axis of Resistance, especially Hezbollah; and the continued economic, social, and political duress the regime imposes on ordinary Iranians. Might this corrupt theocracy be the next regime to fall? Let’s hope. Watch the Interview Here .

The Fall of Damascus

December 8, 2024
As I noted yesterday, Damascus will fall if Assad flees. This morning it is believed that Assad has left the country and the rebels control the capital. The question now is “who” and “how” will Syria be governed? Right now we should celebrate Assad’s fall and this strategic defeat for Russia and Iran. Watch the Interview Here.

Never Forget

December 7, 2024
Never Forget. And let’s also not forget the key to preventing a future global conflict like WWII — a strong, modern, and capable U.S. military aligned with equally capable Allies/Partners, all of whom are committed to President Reagan’s mantra of “Peace Through Strength.” 

Syria and a new order in the Middle East

December 2, 2024
As I told Kasie Hunt, "I was a little surprised ... I think it is significant ... you can see the chessboard in the Middle East is changing around right now in front of our eyes." Watch the Interview Here .

Potential Hezbollah Ceasefire

November 26, 2024
Implementation — specifically, ensuring Hezbollah doesn’t return forces to the south of Lebanon as they did in violation of the 2006 UN resolution that ended that conflict — is critical to the success of this agreement. Glad that Israel asserted the right to enforce this agreement via the IDF if violations do occur. Watch the Interview Here.

Thoughts on President Elect Trump's Cabinet Picks

November 25, 2024
See my thoughts on two of President-elect Trump’s national security nominees, their path ahead to Senate consideration, and some of the tough questions each will face as this important constitutional process plays out between two coequal branches of American go. Watch the interview Here .
