In an exclusive interview on Saturday, former President Donald Trump said that Russia's invasion of Ukraine could lead to a world war and that President Joe Biden's administration would have to put more pressure on Moscow than just issuing sanctions.

During a conversation with Fox News Digital at the site of the Conservative Political Action Conference in Florida, the former president said that the invasion never should have happened.

He said that it is a horrible thing and that there is great bravery being shown.

When asked if he had any words for Putin, Trump blanked out.

The former president said that he had no message. It should not be happening.

Thousands of people, I mean, this can lead to much bigger than this one area. This could lead to a lot of other countries.

During his time in the White House, Trump was criticized for his close relationship with the Russian leader.

He said that you never know how a world war will start. You end up in a world war.

This is a very dangerous time for our nation.

The US, Canada, and its European allies agreed to block Russian banks from the dominant system for global financial transactions shortly before the interview.

Trump wasn't impressed with the move.

He said that they will have to do more than just sanctions.

The former president continued to criticize Biden for the manner in which the US withdrew from Afghanistan, even though his administration laid the groundwork for the eventual exit.

It was a good thing to get out. The former president said that he had reduced the troop levels in the country to two thousand.

180 people, including 169 Afghan citizens and 13 US service members, were killed in a suicide bombing at the Kabul Airport last August, according to Trump.

The former president said that the Russian leader probably came up with ideas that he didn't have before watching the US withdraw.

When asked what he would have done if Russia invaded Ukraine, Trump had little to say.

I would do things, but the last thing I want to do is say it right now, because I'll give them whatever they need.

There are things you can do that are very powerful.
