>I heard the leader of Nigeria supports Putin but I don't know if it's confirmed.

I'm Nigerian...This isn't true (even though our current leader is an oaf). Most African countries aren't supporting Russia...they're just not actively opposing them, and for the right reasons. We're too poor to attempt any sanctions, and we'll rather maintain as much trade as we can with any country.

It'll be dumb for countries whose economies are in shambles to enact sanctions against Russia like the rich western countries that can afford to weather economic pain in the short term.
