Propelled the instinct for survival to compell Islam to forge various alliances, with the infidels both during World War II and the Cold War (aka WWIII). Such alliances, however, being proscribed by Islam as a matter of doctrine, was necessarily both inconvenient and transient.
The Allies' (i.e., US, UK & France) pact with Stalinist Soviet Union was of a similar ilk; pulling to an uncomfortable embrace otherwise mortal adversaries. It was Patton's genius to have recognized and acknowledged that danger even in the heat of battle.
Like all marriages of convenience, however, the pact is dissolved once the adversity is gone. So while everyone is obsessed with the pursuit of happiness, mostly in the form of decadent materialism and moral torpitude, the proscriptions of the doctrine are brought to the fore.
It might be stretching the reliance on hope over experience to credit Liberal Ideology to have invented Global Warming as an overriding planetary danger so once again doctrinal differences can be considered minor and postphonable to safer periods of planetary bliss when the polar bears are no longer in danger of being washed away and off to oblivion.
Alas Global Warming has become a religion adopted by various governments, including most ominously the attempt to establish a Global Government.
So the moral categorical question of the era is: can Global Warming protect us from the battle cry "Allahu Akhbar"?
