So, Putin is no longer our friend?

No, it is not.

 

Putin is upset at Ukrain. It doesn't seem like he is upset at the USA.

 

In fact, the Falcon missiles and sniper systems that made it possible for Ukraine to blunt the Russian advance were supplied by the Trump administration. There was no significant resistance to Putin before Trump took office.

Has the Biden administration managed to deliver any lethal aid to Ukraine as of this moment?

 

Happens all the time. Here is an example:

“NOVO OGARYOVO, Russia (Reuters) - U.S. President Barack Obama praised Prime Minister Vladimir Putin’s achievements Tuesday, attempting to mend fences with Russia’s powerful politician after criticizing him for Cold War thinking.

Obama went out of his way on the second day of his visit to compliment Putin, a former KGB spy who is the dominant partner in a power “tandem” with current President Dmitry Medvedev.

The U.S. leader said he had a good two-hour meeting with the former Kremlin chief at Putin’s forest residence outside Moscow, where officials said the two men had a frank breakfast talk.

“I am aware of not only the extraordinary work that you’ve done on behalf of the Russian people in your previous role as prime minis-, uh, as president, but in your current role as prime minister,” Obama said at the start of talks.

“We think there’s an excellent opportunity to put U.S.-Russian relations on a much stronger footing,” he said.”
