The US Defense Department’s grand strategy for protecting Taiwan from a massive Chinese military offensive involves flooding the zone with thousands of drones.
So does Israel. Israel receives checks for weapons and armaments they can resell, Ukraine receives loans along with the associated debt. It's a regional power thing for the US, treat certain friendly countries at strategic hotspots in such a way that they hold key industries or resources others have to rely on, creating a situation of mutual dependence and giving an incentive for other countries to also support them. Ukraine has Europe and NATO right beside it, so it's much less on the priority list for the US.
It also creates a bunch of problems, specially when it involves a country that's borderline religious neocolonialism, and doesn't work that well against large world and regional powers that are working together like China, Russia, or even Iran.
Nations will certainly bend over backward to ensure access to strategic resources. Unfortunately for Ukraine, grain isn't a highly demanded resource.
Finding some niche technology or product to specialize in would probably be a really good idea. They have experience with rocket engine manufacturing, though that's not a huge market. I suppose they could always extend that to munitions manufacturing, it seems there's always a market for that... Sigh...
