Over the centuries and millennia, diplomacy has always been the "way out" of allegedly inevitable and fatal and national/international conflicts.
This is why all countries have State Departments, not just Defense Departments. Indeed, millions of Earthlings think all countries should have "Peace Departments".
The Israeli/Palestine conflict is probably the supreme example in recorded history of what happens when diplomacy is urinated on by religious and political fanatics, and a plague on all these houses of hate.
Diplomacy WORKS! Civilization has never been nurtured or evolved by war. War is the certain death of Civilization. Diplomacy is jiggling the key, not nuking the lock -- softly, softly, catchee monkey.
God only knows what would happen if the psychopathic Middle East was rained on by the gentle and healing rains of diplomacy. Instead of diatribes; dialogue. Instead of lies; honesty. Instead of screaming; listening. Instead of rage; respect. Instead of killing; hope.
An infallible measure of social maturity is the degree to which humans (and countries) turn to communication, not violence, to deal with the inevitable conflicts of life. History (and our personal lives) have shown us over and over again that practically anything can be "worked through" when given a chance.
Does this apply to "terrorists"? Well, for openers the very word stops diplomacy in its tracks. Who is calling who a terrorist, and why? Wouldn't it be better to just drop inflammatory name calling AND DEAL WITH ISSUES?
This is what works in business arbitration. When union reps and company lawyers cut the crap and spend an hour or two just being people together, that's when things get done!
So why don't the Israeli's and Palestinians cut the crap for an hour or two and just be human beings together and actually LISTEN TO EACH OTHER -- without unveiled threats and religious hatreds (and as everyone knows, there's no hatred like religious hatred).
