Of course you can transfer coins into any valid wallet address, but the real question is - Can the owner of that address access the coins, and can he use them?
They can theoretically after sending it to intermediate addresses and mixing it but the real question for me is how to be sure you are not being tracked by enemies intelligence for example. I mean you support country X by Bitcoin but your data is exposed and intelligence can track you especially if you use the same addresses or wrote them in a post here or social media.
I believe Bitcoin is a minor currency in conflicts. After the $, we have other FIAT, then drugs, then gold and metals, then cryptocurrencies with privacy mode ON.
