The Trump administration lifted its suspension of military aid and intelligence sharing for Ukraine, and Kyiv signaled that it was open to a 30-day ceasefire in the war with Russia, pending Moscow’s agreement, American and Ukrainian officials said Tuesday following talks in Saudi Arabia.
Sustaining war doesn’t really depend on the economy. They can ignore a lot of things and just keep going. The only reason they have to worry about 10-ish months is they are running low of soviet stocks of things like artillery, tanks and such. However North Korea doesn’t really need/want money to deliver more and so that it is unknown how that continues.
The economy matters, but only in that as people’s lives get worse they will start to become more interested in revolution.
