Kill them.
How do you make someone surrender when they want to die, and have nothing on this earth they care about?
Kill them.
How can you remove islamic terrorists from a country once they are infiltrated, when they hide among the people you are trying to save?
Kill them.
Islamic fundamentalism is like a cancer you simply can't beat. You can kill it, but only by killing the patient.
OK. Kill them.
It worked against Japan and Germany 60 years ago and the world is the better off for it, isn't it?
It's a simple solution, but not one we are (for PC reasons) likely to pursue. Therefore, we will be awash in our own blood long before they are awash in theirs.
But Japan and Germany were countries who were at war with us. Once we had driven the Germans from France, and back to their own country, we could indiscriminately kill people in the country. Same with Japan, we could kill them and if there was collateral damage it was still our enemy.
In Somalia, there is an elected government, supported by the United Nations. Then there are the Islamic terrorists, who have infiltrated and are intermingled in the population. Ethiopia has invaded to support the elected Somali government, so they couldn't just blow up the country.
In Iraq, we were trying to "save" the Iraqi people from Saddam, and now from the terrorists and insurgents, so when we kill civilians we are killing the people we are trying to protect.
That's why I think of it as a cancer, hiding among the good cells, and you have a terrible time killing off the cancer without killing the good cells around them.
Like Israel trying to fight "Hezbollah" rather than fighting Lebanon. If they had been fighting Lebanon, then when Hezbollah hid among the civilians Israel could have just bombed them anyway, because they'd be attacking the enemy.
But because they were fighting a faction in Lebanon, and not the government, they had to worry about collateral damage.
