The more likely scenario:
Continued anti-Americanism throughout the world..
U.S. remains in the United Nations, but ends the "honor" of host country.. This after a confrontation concerning membership on the security council and human rights violations.. The UN is forced to move it's headquarters.. France refuses to take them in.. UN is finally situated in Geneva, Switzerland..
Islam takes over in europe.. Muslim immigrants begin to realize that while they are still a minority in most nations, there is no actual military force in europe capable of stopping them.. Immigration increases 100-fold.. european governments fall like bowling pins under the onslaught..
Russia is one of the few "european" nations to resist the influx of Islamic radicalism.. It resists with deadly force and ethnic cleansing..
Indonesia, and other nations in Southeast Asia follow the lead of Russia, and begin their own ethnic cleansing of Muslims.
China refuses sanctuary for muslim refugees.. So does Australia, New Zealand..
Islam's large presence in Africa results in an uneasy truce with non-muslims, but it is only a matter of time before war breaks out there as well..
South America, in the midst of a severe depression, with many of the continent's governments in bankruptcy, is faced with revolutionary forces at every turn. Criminal elements, especially the Drug Traders, take advantage of the situation and finance the rebels, recieving "protection" from government forces in return..
China and North Korea begin a "frenzy" of production, mainly military products.. many are sold to the parties in conflict, mostly to the muslims, but not exclusively..
North Korea is financed by China in order to allow it to increase it's production capacity.. No longer obstructed by the need for food or money, N.Korea becomes one big forced labor camp, turning out missiles and nuclear warheads at a ferocious pace, as well as more standard military hardware.
Southern Europe, now totally in Muslim hands, declares itself an Islamic republic...
Northern Europe and Russia find themselves with their backs against the wall.
The new Islamic Europe declares Jihad against the north.. Their mission: to finish the job and make all of europe muslim..
Mexico has fallen to Marxism.. Canada has fallen to Socialism and declares itself "neutral" concerning all international affairs..
OPEC and the arab states declare an international oil embargo against all non-muslim states.. Oil producing nations of Brazil and Mexico, not surprisingly, join OPEC's embargo..
World War 3 erupts...
Half of U.S. military forces are still in the Middle East or europe..
China/N.Korea launch a massive sea-attack against the western canadian shore.. China's aim: to put 3 million asian soldiers on the North American continent..
U.S. forces put up a strong defence but are overwhelmed by superior numbers, not military force or technology..
Most of China's Naval forces are destroyed. China is undettered. Every available sea-going vessel is packed with soldiers, weapons and ammunition..
Destination: Western Central America,Mexico, America,Canada, Alaska..
Some American Naval forces remain, but are ordered to retreat in order to defend the western U.S. shoreline..
The Chinese/N.Koreans are largely successfull.. A beachhead is established.. Western Canada is unable to put up any real defence.. It barely slows Chinese forces as they advance..
Simultaneously, Chinese forces disembark at the Panama Canal, the shores of Central America and Mexico.
They immeadiately begin to move north into southern and central western Mexico.. There is little resistance..
The U.S. is now threatened from both the North and the South..
Two-thirds of the world's population dies in the next 15 years..
..
Just my opinion.. I might be wrong..
In the next year, scientists note just how fat Pacific sharks are.
Also, where will they get this 3-million-man army? China's downsizing their military from 2 million to 1 million (because they can't afford a BIG army and a GOOD army at the same time). Additionally, the Chinese military has a critical role in Chinese domestic security (i.e., in putting down unrest before it becomes revolt). Stripping the homeland to support foreign adventures practically invites the citizenry to overthrow the ChiCom government, which doesn't have an infinitely deep pool of trained manpower.
U.S. forces put up a strong defence but are overwhelmed by superior numbers, not military force or technology..
How? You haven't explained how the Chinese actually get ashore in the Western Hemisphere. Access to the world ocean is solely with the sufferance of the United States Navy.
Most of China's Naval forces are destroyed.
Try "all of them are destroyed."
China is undettered. Every available sea-going vessel is packed with soldiers, weapons and ammunition.. Destination: Western Central America,Mexico, America,Canada, Alaska..
Actual destination: bottom of the Pacific Ocean.
Some American Naval forces remain, but are ordered to retreat in order to defend the western U.S. shoreline..
And the ChiCom invasion fleet gets sunk in the Pacific.
Navies exist to protect shipping. Without any naval force in the Western Hemisphere, the Chinese invasion fleet dies before hitting the coast. Look at the size of the Pacific Basin--a ChiCom invasion fleet would be sailing literally halfway around the world!
Just out of curiousity: When did "stunning ignorance of reality" become an "opinion" worthy of respect?
Your scenario is as laughable as the other nonsense.
Or maybe it's a setup to explain why we're dealing with Iran... We don't have choices between good and better -- we have choices between bad and much worse. The world's fright night.
Boy, thats one hell of a opinion!
