That's the path to victory. Such a policy wouldn't take long to change the dynamic of this war. But as long as one side seeks "surgical" strikes and pursues diplomacy, while the other blows up anything and everything it can, evil will always have the advantage.
There is something else that must be cut off if the West hopes to defeat possibly the worst enemy it has ever faced. While Americans worry about large numbers of Mexicans crossing the southern border, we should also do something about the Muslim invasion and the sedition that is taught in some Islamic schools. Mosques and Islamic schools are multiplying in the West. Those that teach and preach hate and sedition should be closed and their clerics arrested or deported. Even those that profess to be proponents of "peaceful" doctrines can be fronts for terrorist activities.
The recent arrest in Toronto of some alleged terrorist conspirators and their suspected links to terrorists in Georgia shows that the virus is spreading. Why do the United States, Canada, Britain and much of Europe admit radical Muslims and their clerics from countries where this virus has flourished? Why do they let schools proliferate that have as their goal the overthrow of their host country (the alleged Canadian terrorists apparently were homegrown Muslims)?
When I travel internationally, I am prohibited from bringing home plants and animals. U.S. Immigration asks if I have walked on farmland or been near livestock. The same principle should apply to islamofascists. Why are we letting one virus in and keeping out plants and animal bacteria?
If we don't figuratively (and perhaps literally) cut off their heads, we have seen ample evidence of their intention to cut off ours.
