Yeah UG might be in trouble but nothing significant to rattle M7 hardened thug. Few visa freezes for NRM generals or electoral commission poodles. M7 as he go senile will likely be inherited by the army commander son - or overthrown by NRM like Mugabe.
Of course i don't buy that "Biden is crazy" - i see him as a softie. Obama and Hillary Clinton were the hawks who wrecked havoc in Middle East and North Africa. The ongoing Libya, Syria, Iraq, Yemen horrors are likely to make Biden very careful. I suspect and hope Kamala Harris is relatively hardcore with her rough prosecutor record of locking up M23 drug dealers here in California. Kamala's foreign policy views are unknown.
The incoming SoS Tony Blinken is at best a foreign dove. Best known for assuaging policies than confrontation. Blinken has been Biden's foreign advisor so far and indications are containing China through "peaceful and legal means" - obviously it include sucking up to friendly dictators in UG and Egypt.
M7 strongest carrot is Biden's deep love for women, LGBT and such liberalism - which M7 and Kagame milk by propping flowegirls as ministers, MPs, etc. With female VP, expect foxy M7 to ease anti-gay laws, appoint lesbian UN ambassador, probably top up with LGBT rights committee or such.
Geopolitically UG strongly leans US/West which makes it a strategic misnomer for western powers to want M7 out. Bobi Wine could lean China so don't be naive about western hypocrisy. The incoming US admin has in fact dented democratic, economic and geopolitical credentials and has bigger fish to fry.
Biden is crazy - and doesn't like dictators.
2ndly it depend on Uganda - if they riot - leading to death and carnage - sanctions will come.
Definitely Museveni could find himself in unfamiliar territory like Moi did in 90s.
Sanctions will hit Uganda hard because their budget is still donor funded.
any sanctions on Magufool? after 85% clean sweep. Earlier kagame made a cleaner sweep at 98%
