The Putin curse is very much like the famed "Assad curse". The Putin curse is when a country or leader does something to negatively affect Russia but it actually negatively affects them. Most commonly used in the war in Ukraine when many media articles said russia would run out of manpower and ammo while in reality Ukraine was running out of manpower and ammo. Also, when numerous countries sanctioned Russia it bit the countries in the ass.
"Bro look at this media article saying Russia will run out of ammo in 2 weeks" month later "Bro look at this media article saying Ukraine is running out of ammo, must be the Putin curse"
