Neither, many are going to become refugees and stay in western Europe for the winter. Some will return, others won't. Without energy, you can't cook food, so there'll be more disease irrespective of how the food is stored. Ukraine also has large stores of grain from the last harvest and with a much smaller population to feed, more can be exported. But the next harvest will be far smaller, there are fertiliser shortages and many of the working age men are serving in the armed forces while the women have left.
Hospitals also need electricity. Many doctors are working age and may need to support the armed forces. Many soldiers with battle wounds need treatment. The young population who has left the country needs little treatment, but the elderly have remained. Many won't be able to get adequate treatment this winter. The Russian strategy is very cruel, but it will have a profound effect. Modern society doesn't work without electricity.
I'm still of the belief that there's no chance that the current tactic of bombardment of Power infrastructure will cause Ukraine to yield. There's much further to go for human suffering before we are even anywhere near the bottom. If all it took was for some roads and transformers to be destroyed for a country to surrender the US would've won every war since WW2, fundamentally 50kg of explosives on a moped engine is just not going to cause that much damage.
Currently Russia does not have the capacity to deal a decisive blow on the battlefield and Westen aid continue to flow uninterrupted into Ukraine, despite all the optimism in this thread civilian support for Ukraine remains at a high across the West, of course this new tactic of mass strikes is very disruptive to civilian life, but that alone would not win a war.
It’s pretty easy when there is no food stored away, a war is happening right now, the electric grid is all but done, the only port there being Odesa is likely to not only a target but the grains have to go out to help the EU whilst leaving not much for themselves. So yah, if this war continues and the USA gets physically involved, well maybe it will be quite easy to stave to death under those circumstances if Zelensky doesn’t stop with his nuclear talk and start negotiating and stop being backed doored by BoJo. Heck given that Russia is most certainly not sending fertilise their way nor fuel and such, how in Gods name are they going to plant grain for the next year or the year after and not have these fields blown up by missiles and drones
If 7 million Ukrainians have fled the country, then there's literally almost 20% less mouths they need to feed, the ground of Ukraine are some of the most fertile on Earth so I'm not even sure how they are going to starve. If anything, they can probably feed themselves for years just from the stored grain at this point.
I will never understand why people desire so much that Ukraine enter peace talks, there's no mechanism for Russia to not reneging on any agreement once it is made and they have rebuilt their military, since the west has already gone as hard as they can with sanctions. Why would you enter any sort of peace talks when this sort of stuff is on their TV? (Mods remove if inappropriate)
