That article does not say what you (and possibly the author) think it does.

> The United States on Thursday temporarily lifted sanctions on Russian oil that is currently at sea

This is weird phrasing, and for a reason. Oil at sea has typically already been sold! Lifting sanctions on it does practically nothing.

That decision was out of self interest. The US will do whatever it can to try to stop Iran succeeding in their strategy to raise the price of oil.

So no. Not proved wrong in my opinion.

Did you collude with Putin today by not traveling to Russia to attempt to assassinate him or die trying?

Did Biden collude with Putin by not launching nuclear attack against Russia when he was President?

Did Obama collude with Putin when he secretly transmitted a promise to be "more flexible" with him after his election presumably in return for unspecified favors, then later meekly capitulating to Putin's annexation of Crimea?

Just because somebody does not take the most drastic or damaging action they possibly can against another, does not mean they are colluding with them or sympathizing with them. What an infantile worldview.
