Ukrainians have mined odessa
Ukrainians mined odessa, but forgot the exact locations, but they have blamed Russia for weaponizing food. If Russia is to be blamed perhaps their best move now is to put their own mines off odessa, since they would be blamed anyway.
The mines could be cleared easily enough. But as it stands, Putin will simply use the free passage to attack Odessa.
He's using starvation in Africa as a weapon of war. Because Putin doesn't give a flying f**k about anyone except himself. Not even the bewildered Russian conscripts he sends into battle with no clue what they're there for.
