So is invading other countries...which they did BEFORE any embargo’s were in place. GO READ A REAL HISTORY BOOK.
I was simply stating a fact (e.g. how an embargo is defeind under international law) that applied to U.S/Japan relations. As to your point, plenty of countries in the wold have invaded "other countries" in the last few decades. Are you suggesting that we should go to war with all of them? If so, I may need a history book but you'll need a whole factory of money printing presses to pay for that!
