During his "My Take," Tuesday, "Varney & Co." host Stuart Varney reacted to President Biden authorizing Ukraine's military to use American-made missiles inside Russian territory, a move that pushed Vladimir Putin to respond and "rattle his nukes."

: Presidential decisions have consequences. Even after losing, Joe Biden will stay in office for nearly three months. 

He can and will keep making decisions with great consequences.

Over the weekend, he authorized Ukraine to use American-made missiles to attack deep inside Russia.

Now look what's happened. Last night, some of those missiles were fired into Russia.

Immediately, Putin responded. He revised the rules for using nukes. He has lowered the threshold for first use. This is an escalation.

The trouble is, Biden is not in good shape. His continuing decline is gaining speed. He missed a photo op with world leaders. 

Reporters eventually found him behind a palm tree. He just doesn’t appear to know what's going on.

Putin knows his weakness. So he takes advantage and rattles his nukes.

Donald Trump can't reverse the missile decision. He's not the president yet. Putin is exploiting America's dilemma.

We have an infirm president, in the twilight of his term in office, making it difficult for his successor.

You have to ask. Is Biden making these decisions? Is he competent to make these decisions?

But it’s done. The missiles have been used. Putin has escalated and President Biden, with only days left in the Oval Office, has made it difficult for his successor. 

It really should not be like this in a peaceful, orderly transition.
