Trump is not good and definitely hawkish is every way, but at this point it is no longer deniable that Biden has crossed the line that perhaps most American presidents wouldn’t dare to cross.
Trump liked to pretend to be a master businessman by persuading the Europeans to spend 4% of their GDP into defense, only to be laughed at. Biden literally started a war and forced Europe into austerity to pay for their defense spending (while killing hundreds of thousands of Ukrainians and Russians at the same time).
Trump tried to persuade Merkel to build LNG terminals to get rid of Europe’s Russian gas dependency. The project eventually went nowhere because nobody took him seriously. Biden literally bombed their gas pipeline and ended European prosperity for the century (yes, the European economy is a dead zone now. It is not going to come back for a long time).
Trump started petty trade wars with China, which were reciprocated proportionally by the Chinese. Biden literally started a tech sanction against China that has no proportional response, and ended the friendly relationship between US and China. There is no reconciliation between the two at this point.
Biden raised the interest rates to 5% in one year and plunged many countries into famine and energy shortage, exacerbating debt crisis across the developing world. Hundreds of millions of people (if not billions) in the Global South are literally suffering to slow the decline of the US Empire.
These are the lines that I doubt even Obama would dare to cross. Whether you like it or not, Biden seems very keen on setting the world on fire and starting fights with the entire world. And he might very well win, that’s the scariest part.
