Tell that to the Indians.
As it turns out, countries sign treaties that work to their leaders' advantage. If a country's leaders think that it's to their advantage to ignore a treaty they'll do it in a heartbeat. Everyone involved understands this. No trust is involved. Right and wrong are no part of the equation. Countries keep treaties either because it's to their advantage or because the country they've signed the treaty with is powerful enough to make them, period.
See, this is another similarity between you and Gonz. You both seem to think that some utopian dream world (not the same one, of course
) can somehow be magically brought about. I keep trying to tell you both, not as long as there are humans in it.
