Joe Biden versus Donald Trump domestically: Joe Biden has been in government for 50 years, has worked with segregationists, has written the crime bill, has bailed out Wall Street, has worked with credit card companies and banks. Donald Trump has given tax cuts to the rich, has done nothing about COVID-19, has given even more bailouts to the 1%.
Joe Biden versus Donald Trump internationally: Joe Biden has voted for the Iraq war, has ramped up two to seven wars under Obama, has gone after Edward Snowden and has cancelled his passport; mass surveillance and war on terror expanded under him and Obama. Donald Trump has pulled out of so many international accords (JCPOA, WHO, UNHCR, Paris climate accords), has assassinated General Soleimani and Abu Mahdi, has bombed Syria in 2018, has put Caesar Act sanctions on Syria, has imposed sanctions on Iran and Venezuela, has attempted a coup in Venezuela with Silver Corps, a coup against Bolivia, has gone after Assange.
This shows that, domestically and internationally, Joe Biden and Donald Trump are both warmongers, they serve the military and intelligence establishments and nothing will fundamentally change under either of them. There is no difference for people in the US, and especially none for people outside the US. The US Empire continues to oppress other nations with war, sanctions and occupation.
