trump carried on with existing US military involvement with overseas wars as well as negotiaiting with terrorists, whilst excluding the exisiting government. He also signalled intent contrary to US strategic interests. Yes, IS was mostly destoyed whilst he was in power, but that was just a continuation os existing strategy. Unfortunately he attempted to betray the Kurd who were the main infrantry combatants against IS. So far as I'm aware Biden Administration has not committed US forces to any new war or generated new threats.
