In theory, yes, and it has worked sometimes ( the EU). But as many agressors have shown time and again, you can't count on anything but brute power in the end. Neutrality ( Belgium), UN ( Ukraine), they don't work sufficiently well.

As a sibling comment says, Si vis pacem para bellum has withstood the test of time.

Of course the US wasting money having 10 aircraft carriers and 10 "mini" aircraft carriers ( the same size as other countries' 1-2 aircraft carriers) doesn't really fit into that and certainly isn't for defence.
