>cryptocurrency defeats current international sanction tools.

If one values international law, or the, "international order" (as Secretary of State Blinken put it, without irony), then a bright line needs be drawn between, "international sanction tools" that are used by the UN and the unilateral sanctions issued by the US.

>Will Bitcoin lead to more war as a result of weakening the power of sanctions?

Bellicose nations have always issued demands to other sovereign nations backed by the threat of illegal wars of aggression. Will the ability of targeted nations to avoid being starved to death via the use of bitcoin lead to more war? Possibly, but is the problem there really bitcoin, or rogue nations who consider themselves above international law?
