From my point of view, the terrorists will never stop, and we’ll never kill enough of them, and their weapons and tactics will improve without end. At some future point, only Draconian methods will end the threat. That’s why I predict that some hawkish Christian leader will emerge with an idea for eliminating Islam. And as horribly evil as that will be, no one will have a better idea.
Just to be clear, I’m not advocating that solution. I just predict it will happen.
I think this is a reasonable prediction.
The Israel/Hezbollah conflict is an example of the likelihood of this happening. Israel doesn't have the balls to completely wipe out Hezbollah (like blowing up Mosques, intentionally targeting civilians, attacking anyone who resupplies Hezbollah), so eventually there will be a ceasefire, and then Hezbollah will be resupplied by Iran and Syria, and more Shiites will join up because they were inspired by Hezbollah's ability to stand up to the Jews. Eventually Hezbollah will be even more powerful than it was before the attack.
Now some will say "ah ha! This means it was a mistake for Israel to attack." This ignores the fact that Hezbollah was growing stronger and stronger before the Israeli attack. Shiites were joining up inspired by Hezbollah's ability to kidnap Israeli soldiers and get away with it.
So you see, whether Israel does nothing, or attacks Hezbollah half-hearted way (the current strategy), Hezbollah grows stronger.
