President Donald Trump ought to demand the unconditional surrender of the Democrat Party as he did of Iran.

That is because he has metaphorically speaking wiped out the Democrats as he did the nuclear bomb bent bullies in Iran, and their plan to first nuke Israel and then the United States.

If you thought the Democrat Party and its leaders had had hit rock bottom defending illegal immigrants, including the violent criminals among them from deportation, you must think again.

Pretty soon Democrats will be protesting against the arrest and deportation of untold numbers of unvetted illegal immigrants from Iran who crossed into the country thanks to Joe Biden’s open borders.

Did they come into the country to seek work, or to set up sleeper cells?

Perhaps these sleeper cells are about to become active now that Trump is prepared to do the world a long-awaited favor – despite a cease fire — and wipeout the leaders of Iran off the map.

You can count on Ayatollah Ali Khamenei and the mullahs to cheat no matter the agreement they make, as they have done in the past.

If the smashing success of the extraordinary and undetected B-52 bunker busting raid on the country’s nuclear infrastructure is any indication, it would not take long to destroy what is left of Iran anyway.

Meanwhile, doubling down on stupidity, the Democrats attacked Trump for eliminating—or at least setting back—Iran’s capacity to complete construction and delivery of nuclear bombs.

The militant Islamic terrorist government of Iran, which has been waging terror and war on the United States for more than forty years, has killed close to as many Americans as the Japanese did during their sneak attack on Pearl Harbor Dec. 7, 1941, which led to war with Japan. Some 2,335 American sailors and soldiers died that day.

The U.S. and the Allies in their defeat of Nazi Germany and Imperial Japan in World War II insisted on an unconditional surrender, which they got from both countries. This meant that the U.S. and the Allies set up the terms for peace, which is what they did.

In no other war since then, not the Korean War, the Vietnam War, the two Gulf Wars, or any other wars the U.S. has since been involved in has the president insisted on or even mentioned “unconditional surrender.”

Until now.

While we may not call for regime change and the ouster of Khamenei and the religious fanatics who have spread terror around the world, it is what will happen.

Unconditional surrender means that the victor dictates who will run the defeated nation after a war, as happened in Germany and Japan following their unconditional surrender in World War II. It was a regime change for both countries. Otherwise, nothing changes.

In one fell swoop, though, Trump not only saved Israel and the Middle East from a nuclear Armageddon, but possibly western civilization as well. It was an event unlike any other in military history.

It was an extraordinary mission that caught the attention of the world, including China, which may have second thoughts now about invading Taiwan, and Russia, which is caught in a World War I-like stalemate in Ukraine.

And unlike the cowardly ambiguity and doubletalk toward Iran and its nuclear program in the past by Barack Obama, John Kerry, Joe Biden and Antony Blinken, Trump was clear as a bell.

“It’s very simple,” Trump said. “Iran cannot have a nuclear weapon.”

While it is true that other nations have nuclear weapon capability, Iran is the only country that has openly vowed to use a nuclear bomb on its enemies, Israel and the United States.

The hateful religious zealots in Iran have been promising death to both for almost fifty years and if allowed to do so, will continue for another fifty.

Which is why the Khamenei and the rest must go.

If not, there will be no unconditional surrender and it will all be for naught.
