That's a nice sentiment that sounds good in theory, but it falls far short in the real world.

Words didn't cause peace in Japan, Italy and Germany. War did.

Words didn't persuade Saddam to leave Kuwait in 1991. War did.

Words didn't end the fighting in the Balkans. War did.

Words didn't persuade the Taliban to end their repressive and murderous government. War did.

A treaty is only a piece of paper unless it is backed up by honorable intentions and quite often, the force to back up those intentions. Hitler and Stalin signed a non-agression pact in 1939. That didn't stop Hitler from invading the Soviet Union in 1941. The US government signed countless treaties with our Native Americans and ultimately broke every one.

One seemingly forgotten historical tidbit is why so many Jews decided in the late 1800s to start the Zionist movement back to Palestine, namely the virulent anti-Semitism, particularily in Europe, as highlighted by events like the Dreyfuss Affair.
