I'm not sure if "impressed" is the right word for what you're trying to describe. I'm just going to address the first example to try and figure out what you mean.
Stuff that has big value is worth a lot of money. Thus money is based on people being impressed.
This sounds tautological. Is "big value" not synonymous with "worth lots of money"? I'm reading this as saying "Something that is worth a lot of money is worth a lot of money, and people are impressed by things that are worth a lot of money, so if people are impressed by something, it will be worth more money."
Does he even need to send them anything? Doesn't he just have to say a few words to give Ukraine permission to build their own? Although I guess if they lose US support, they wouldn't need permission anymore.
