NATO is not a threat to him. NATO is a defensive alliance.

What Putin wants is a binding document that commits NATO countries and Ukraine to never have Ukraine as a member. And that is giving up not just the sovereignty of Ukraine, that`s giving up our own sovereignty.

I think they were smart, clearly leaving the window open for diplomacy but making it clear we`re not going to trade away basic principles of democracy and sovereignty.

Everything got worse.

Diplomacy is the only path forward to stop Iran from getting a nuclear weapon.

Ultimately this is up to the Ukrainian people as to whether they want to be part of a military alliance with Russia, or a military alliance with the United States, and Europe.

This would be, in my mind, a massive strategic mistake akin to the invasion of Afghanistan by Russia in 1980.

We need to make sure that Russia understands, there is going to be a devastating blow to their economy if they walk into Ukraine.

Ukrainian people have decided that they want to be part of Europe, they want to be part of NATO.

We have never before given Vladimir Putin, or any other world leader it veto power on whether a Democratic nation wants to allow themselves to the United States, or a foreign power. We are not going to start now.

This is a signal of Russian weakness, this potential invasion of Ukraine.

The United States has pledged $308 million, less than 10 percent of that total.

I believe is President Biden made the right decision to remove our remaining troops from Afghanistan.

The scenes that accompanied our withdrawal were really hard to watch and there is no doubt mistakes were made.

There is a growing humanitarian nightmare metastasizing in Afghanistan and it demands our nation's attention.

The overnight collapse of the Afghan army and the government was, to me, proof that 20 years of nation building had failed.

The Biden administration made what they could out of a pretty terrible situation.

I'm glad that the U.S. is engaged in this intensive diplomacy, I'm hopeful that it will bear fruit. At the same time, it is based upon a set of concerns articulated by Russia that are imaginary.

Vladimir Putin is likely getting really horrible advice. Reporting suggests that some are telling the Russian president he`s going to be created as a liberator if he enters Ukraine, at least if he moves further than he already is in…

But to the extent that our couple European nations that right now aren`t willing to do the tough stuff, it might be because they don`t believe Russia is actually going to go through with this. And when they do, and when the cell phone…

To the extent there are a couple European nations that right now are willing to do the tough stuff. It might be because they don`t believe Russia is going to really go through with this.

He essentially is asking us to give Russia a veto power over who enters NATO. And that is, quite frankly, contrary to the entire essence of democracy.

Vladimir Putin is likely getting really horrible advice. Reporting suggests that some are telling the Russian president he`s going to be created as a liberator if he enters Ukraine.

When the cell phone video has come out of all the awful atrocities, that set sanctions. It might be a lot tougher than Putin really thinks it`s going to be.

I think this is going to be bloody. I think it`s going to come with a huge cost, both in terms of lives to the Russian army, but also in rubles and dollars to the Russian economy.
