The Pentagon said Monday there is no letup in the Russian military buildup along Ukraine’s border and it’s reached the point where President Vladimir Putin now has a complete range of military options.

Speaking at a briefing with reporters, Pentagon press secretary John Kirby said over the weekend, Russia continued to move additional ground forces around Belarus and along Ukraine’s border.

“He’s got a full range of military capabilities available to him, which only continue to increase the number of options available to him, whether if he decides to move militarily,” he said.

Kirby said discussions are continuing about U.S. troop deployments to eastern flank NATO countries but he said no decisions have been made.

“We’re going through the rigorous work of providing options for the commander in chief, should he decide to do that, where and when he decides to do that,” Kirby said.

“What we’re focused on is the the the very real security commitments that we have…to our NATO allies should Mr Putin decide to make or to exhibit threats against the alliance,” he said.

“We want to make sure that he understands unequivocally that that’s not going to be acceptable in the United States. Will we’ll fight to defend our, our NATO allies and our commitments to our allies on the continent,” Kirby added.

The Pentagon spokesman also addressed North Korea’s test-launch of an intermediate-range ballistic missile capable of reaching the U.S. territory of Guam, the North’s most significant weapon launch in years.

Kirby said the U.S. is constantly looking at its “force protection there on the peninsula and in the region.”

He said while the Biden administration hopes North Korean leader Kim Jong Un will chose diplomacy over provocation, “here at the Department of Defense, we’re going to do what we have to do to be ready on the peninsula.”
