More than three decades have passed since the United States military detonated a series of underground nuclear explosions at the Nevada Test Site.

Yet in a major development, President Donald Trump has ordered that the testing of nuclear weapons will resume. 

Trump says testing "will begin immediately"

According to the Daily Caller, Trump announced the policy change in a post made to his Truth Social platform on Wednesday evening.

"The United States has more Nuclear Weapons than any other country. This was accomplished, including a complete update and renovation of existing weapons, during my First Term in office," the president wrote.

"Because of the tremendous destructive power, I HATED to do it, but had no choice! Russia is second, and China is a distant third, but will be even within 5 years," he continued.

"Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis," Trump explained before stating that the "process will begin immediately."

Russian president unveils nuclear torpedo

The Daily Caller noted how Trump's remarks came in the wake of comments made by Russian President Vladimir Putin about a newly developed nuclear-capable torpedo known as the Poseidon.

"For the first time, we managed not only to launch it with a launch engine from a carrier submarine, but also to launch the nuclear power unit on which this device passed a certain amount of time," the Associated Press quoted Putin as telling Russian television viewers.

"In terms of speed and operating depth, there is nothing like this unmanned vehicle anywhere in the world, and it’s unlikely that anything similar will appear in the near future. And there is no way to intercept it," he maintained.

Putin further stressed that the nuclear reactor which powers the Poseidon is 100 times smaller than the reactor found on a nuclear submarine.

What's more, he noted how the destructive power of its payload "is significantly higher than that of our most advanced Sarmat intercontinental ballistic missile."

Trump notes that Russia is still fighting in Ukraine

Meanwhile, Fox News reported that Trump criticized his Russian counterpart when speaking to reporters aboard Air Force One.

"I don’t think it’s an appropriate thing for Putin to be saying either, by the way. You ought to get the war ended," the president said in reference to Russia's ongoing war in Ukraine.

"A war that should have taken one week is now in its soon [to be] fourth year. That’s what you ought to do instead of testing missiles," he added.
