Winston Churchill served in the army in both Pakistan and the Sudan, fighting against Muslims. During an encounter in Makaland, Churchill was in the vicinity of a surrendered British soldier who was surrounded by Pashtuns, and hacked to death with a knife.
I think Churchill understood Islam well:
'The Hun is always either at your throat or at your feet.’
This behavior is religiously sanctioned by 8:65-66:
O Messenger. rouse the Believers to the fight. If there are twenty amongst you, patient and persevering, they will vanquish two hundred: if a hundred, they will vanquish a thousand of the Unbelievers: for these are a people without understanding.
For the present, Allah hath lightened your (task), for He knoweth that there is a weak spot in you: But (even so), if there are a hundred of you, patient and persevering, they will vanquish two hundred, and if a thousand, they will vanquish two thousand, with the leave of Allah. for Allah is with those who patiently persevere.
When Muslims are weak, they are allowed to beg (or claim victimhood). When they are strong, they are bound to kill, subjugate, or convert you. Churchill understood this. So did John Quincy Adams. President Bush is too weak at this point to accept reality.
