He has a lot of fence-mending to do with allies alienated by Trump. What is his foreign policy?
From what he's saying (and US Presidents have a poor track record at keeping foreign policy plans, so take with a grain of salt)
1. Stay in the WHO and fund efforts to handle COVID.
2. Do nothing new on China because our economy can't afford it.
3. Rejoin the Paris agreement and try to slow down carbon emissions
4. Move away from justifying the use of nuclear weapons for retaliating against non-nuclear strikes and keep the New START treaty going.
5. Undo the mess Trump made with reneging on the Iran treaty and leaving Europe to clean it up.
6. Pull away from Saudi Arabia and petro-wars like the Yemen disaster (which his former boss kind of got us into, so we'll see).
7. Continue to muddle around in Afghanistan until it implodes, then abandon it.
8. Same for Iraq, Syria, etc.
9. Sigh and roll eyes when N Korea launches a new missile.
That's a pretty full plate. We haven't even gotten to Africa or the Americas yet. Honestly, if he has a foreign policy anything similar to the 11 presidents before Trump most countries would be happy.
