Here's the list; I'm gonna group some of these together for the sake of brevity:

Implementing a Nuclear Posture Review with a more aggressive stance toward Russia, which CNN itself called “its toughest line yet against Russia’s resurgent nuclear forces.” Withdrawing from the 1987 Intermediate-Range Nuclear Forces Treaty. Ending the Open Skies Treaty, which allowed both sides to conduct reconnaissance flights over one another’s territories. Putting sanctions on Russia in response to "human rights violations" and their actions in Crimea and eastern Ukraine, as well as "interference in the US elections". Then more sanctions which targetted various high-up Russian officials and oligarchs, which Vice says were "the most aggressive sanctions yet." Then two rounds of sanctions in response to the Skripal poisoning, and expelling 60 Russian diplomats. Then more sanctions due, again, to Russia's annexation of Crimea. Then yet more sanctions, this time on Prigozhin and friends. Then secondary sanctions on China and Turkey for purchasing Russian S-400s. Forcing RT and Sputnik to register as "foreign agents". Refusing to admit that Crimea is part of Russia.

Threatening sanctions on Germany if they build Nord Stream 2.

Arming Ukraine, in which Trump was actually more hawkish than Obama was. Selling ~$5 billion worth of Patriot missiles to Poland, and 1000 troops. Sending Abrams tanks to Estonia. Putting NATO warships in the Black Sea. Training Polish and Latvian forces to "resist Russian aggression".

Bombing Syria, a Russian ally, for the chemical weapons allegations. Occupying Syrian oil fields, explicitly stating that it's to deny Syria financial resources. Killing Russians in Syria; the exact number is unknown but it could be from a handful to hundreds.

Withdrawing from the Iran Deal to try and hurt Iran, a key Russian ally.

Staging coup attempts in Venezuela, another Russian ally.

The only reason anyone still believes Trump is anything other than insanely hawkish toward Russia is because it doesn’t benefit anyone’s partisanship or profit margins to call it like it really is. The facts are right here as plain as can be, but there’s a difference between facts and narrative. If they wanted to, the political/media class could very easily use the facts I just laid out to weave the narrative that this president is imperiling us all with dangerous new cold war provocations, but that’s how different narrative is from fact; there’s almost no connection. Instead they use a light sprinkling of fact to weave a narrative that has very little to do with reality. And meanwhile the insane escalations continue.

This dates back to November 2019, so it doesn't even cover all of Trump's presidency. It's pretty clear that Trump was much more hawkish on Russia than Obama, and it only seems like Trump was less hawkish on Russia because Biden has been such a bloodthirsty, reckless warmongerer even by the standards of US presidents that he catapulted us to the edge of nuclear war.
