Justifies? Of course not. But it's what governments did for centuries and do up to this day. We can forget about history for a second, but just look at what's going on with China, for example. They've never attacked USA or any Western nation, they're restoring their country after centuries of foreign occupation, making their people life better, expanding markets with their goods, and USA is intended to destroy them. Why? Because they're an economic threat absorbing world markets and pushing USA out, so USA needs to act fast to preserve own dominance over the globe, because China's also building their military, so window of opportunity for military aggression is getting narrower. To make it clear: international politics is never about justice, it's about interests. Those who're relatively strong trying to force weaker powers to submit to their demands. USA is the current King of the Hill, and they're trying their best to not allow anyone to topple them, by invading other countries directly, toppling governments, provoking wars by proxies etc.
