Well... I quite don't see the pertinence of your point I'm afraid.
The issue at hand has nothing to do with "trust" or child plays - but I feel honestly tired to go on and on such basic points.
Equating the IDF to Arafat's death squads is not only morally wrong but also utterly nonsensical. Put a stop on moral equivalence and take 5 seconds to consider the following: if the Israeli government and the IDF were using the same methods and following the same goals as the Palestinians, do you honestly believe there would still be one single Palis ALIVE?
Kind of doubtful if you ask me.
Anyway, all I can possibly answer to somebody coming up with naive statements such as "Hamas terrorists should grow up and learn to share" is a deep and disillusioned *sigh*.
What's the weather like in Dreamland today?
Finally, I don't know about you, but as a French who grew up under NATO's protection, I did learn one thing from the Berlin Wall: it was certainly a hard price to pay for the Berliners, who were on the frontline, but it saved Western Europe from the Communist horror.
If anything, it was a clear statement: stop here or face the consequences.
And I'm still here to tell you that it worked.
