Next guy’s got big shoes to fill

National security adviser John Bolton’s sudden departure from the White House leaves big shoes to fill, as few come to mind who have the expertise, experience and depth of knowledge Bolton possesses on all matters concerning U.S. foreign policy.

I’ve seen it firsthand, interviewing Bolton on numerous occasions on my Herald Radio show covering Israel, the failed Iran nuclear deal, civil war in Syria, the Islamic State, North Korea’s nuclear ambitions and variety of other matters impacting U.S. national security and world peace.

But ultimately, in any administration, it’s the commander- in-chief who sets the agenda for U.S. foreign policy and members of his administration must get in lockstep and share the same vision or relationships are bound to fracture.

That said, it’s imperative the president take a deep breath and choose Bolton’s successor carefully given the myriad grave threats we face that if mishandled can have cataclysmic consequences.

Consider Iran — the world’s leading sponsor of terror — obtaining nuclear weapons aimed at Israel or the United States.

Or the threat of an electromagnetic pulse strike by a foreign enemy that could knock out our power grid, shutting down our entire banking and commercial systems, and endangering millions as few Americans today are prepared to survive on their own with- out access to food, running water, medical care, electricity, transportation and other basic necessities.

The ongoing tariff war with China could lead to increased hostilities ranging from escalating cyber warfare, election meddling and other aggressions worthy of a U.S. response. Then there’s North Korea, which has a penchant for launching a new missile every time the rogue regime isn’t getting enough attention from the president who’s trying to get its dictator to relinquish its nuclear arsenal in exchange for inclusion in the global economy.

Now add to it the ongoing Russia threat, the never-ending war in Afghanistan, radical Islam and the spiraling global humanitarian crisis — just to name a few crises that must be addressed.

Add it up and what Trump needs is a national security adviser with a steady hand. One who shares his vision in ending wars rather than starting new ones, while also being mindful of the balancing act that when America retreats from the world stage dangerous actors fill the power vacuum — making the world a much more dangerous place.

A delicate needle to thread in a complex, volatile world.
