Diana West suggests that it might be in the best interest of westerners to simply allow the various sects, factions, schisms and tribes of Islam to fight among themselves for a while.
There's another Middle Eastern strategy to deter expansionist Islam: Get out of the way. Get out of the way of Sunnis and Shi'ites killing each other. As a sectarian conflict more than 1,000 years old, this is not only one fight we didn't start, but it's one we can't end. And why should we? If Iran, the jihad-supporting leader of the Shi'ite world, is being "strangled" by Saudi Arabia, the jihad-supporting leader of the Sunni world, isn't that good for the Sunni-and-Shiite-terrorized West?
With the two main sects of Islam preoccupied with an internecine battle of epic proportions, the non-Muslim world gets some breathing room. And we sure could use it — to plan for the next round.
To plan for the next round? That is an interesting way of stating that the war between Islam and the modern world will not end until either Islam reforms itself to be more tolerant, or Islam is gone forever from the universe.
Since neither result is likely to occur in the next hundred years, expect the long war (multi-millenial so far) to continue.
