This is demonstrably FALSE.

During his first term, Trump became the ultimate causal agent for every one of the current conflicts with Russia, China, Iran, and Venezuela.

He not only maintained the trajectory of these conflicts as established by previous US administrations, but he dramatically raised the stakes and quickened the pace of the march to war.

Ukraine
In Ukraine, between 2017 and 2021, the already commenced preparations of #TheMotherOfAllProxyArmies were expanded and accelerated to an unprecedented degree.

Almost two-dozen covert US intelligence bases were established throughout eastern Ukraine. Large numbers of Ukrainian armed forces personnel were rotated through US/NATO training programs. Ukrainian officers were instructed in the use of US/NATO communications and intelligence / surveillance / reconnaissance (ISR) data. A chain of command was established from Kiev to US/NATO headquarters at Ramstein Air Base in Germany. US heavy weaponry was pre-staged in Poland, and preliminary deals were made with former Warsaw Pact countries (many of them now NATO members) to provide legacy Soviet artillery, armor, ammunition, and fighter aircraft to Ukraine.

Ukrainian troops were introduced to the use of Javelin Anti-Tank Guided Missiles, M-777 155mm howitzers, and HIMARS Multiple-Launch Rocket Systems.

Some of the legacy Soviet aircraft types in the Ukrainian Air Force were modified to carry and launch US/NATO missiles.

The massive fortification complex in the Donbass region was extended and strengthened.

A few thousand US/NATO "contractors" were integrated into the Ukrainian military – with preference given to the hard-core neo-Nazi brigades, who were considered to be the "elite" units in the AFU.

The strategic focus during the entire Trump 45 administration was to complete the preparation of the Ukrainian military to attack and crush the Russia-leaning separatists in the Donbass, and to then retake Crimea, which the Russians had seized in the aftermath of the 2014 American-led coup d'état in Kiev – and which was formally reassimilated into the Russian Federation as a result of an overwhelming popular referendum vote.
