Ukraine purposely attacked Crimea, multiple times in rapid succession with the help of other countries' and their weapons, with the intention of disrupting security on the black sea, knowing full well it would break their grain deal with Russia.

This escalation fucked over everyone and is intended to make everyone suffer. A world wide wave of deaths may result. The Black Sea is important for shipping, especially grains and their sources, and also Ukraine's grains are important to the world.

Food shortages were already coming, but this was a shitty attempt to ensure Europe couldn't avoid the bulk of the despair by purchasing food from Russia or other countries through the shipping lane. It was important for Ukraine to strangle the whole wold into feeling their pain. The security pressures had began to ease on the Black Sea, and shipping wasn't being halted as much as they would like. These attacks on the Crimea port, roads, and shipping infrastructure, will increase military presence in the Black Sea, making the security concern so high, that no commercial shipper will get insurance to travel through that key shipping route.

This was the time, tiny old Ukraine, bested all of the West, destroying their critical shipping route. This is Ukraine's foot on your neck, not Russia's. I hope you are prepared. Next, bird flu will end your easy food supply of chickens and eggs, almost globally. Chickens were always a luxury that was on borrowed time. The pain will last decades, at minimum.
