The Chicoms have invaded Taiwan, North Korea has launched a huge offensive across the DMZ, Iran has launched massive terrorist attacks against Israel,Venezuela and Bolivia have launched a combined attack on Colombia, and Russian troops are pouring into Poland and Georgia. NATO is dealing with the Russians while the bulk of the U.S. forces as well as Australia, New Zealand and Japan are dealing with the Chinese and the North Koreans. Georgia would basically have to fend for itself while the Colombians would get a small amount of U.S. support. Things look grim for the Allies until the Chinese and the Iranians make the mistake of attacking India to try and knock out its forces before it can think about entering the war. The might of India now falls onto the Chinese and the Iranians as their forces take a severe beating in the intial onslaught of Indian air and naval strikes.
I would think that the combined efforts of the Allied forces, mainly America, Britain, Israel, India, Japan, Australia, Germany, France, Poland, Colombia, Taiwan, South Korea, Georgia, and New Zealand would emerge victorious against China, Iran, Russia, Venezuela, Bolivia, and North Korea. It would be a massive conflict, but it would be over within 18 months. Chavez would wind up being overthrown in Venezuela and the Korean peninsula would finally be reunited.
