North Atlantic Treaty Organization (Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom, the United States, Greece, Germany, Spain, the Czech Republic, Hungary, Poland, Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, Slovenia, Albania, and Croatia).
Shanghai Cooperation Organisation (China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Uzbekistan, Moldova, Afghanistan, Armenia, Azerbaijan, India, Iran, Mongolia, Pakistan, Belarus, Turkmenistan, Turkey, and Sri Lanka).
SCO only has China, Russia, and Iran. NATO has USA, France, Germany, United kingdom, and Spain. That's like when the Miami Heat's big 3 lost to the San Antonio Spurs because they played better team basketball.
Russia would be a problem, but its citizens currently dislike Putin. You could take advantage of that, topple the government and dissolve the SCO.
Our navy has a laser weapons. We also have a lot of nukes, which have a lot more uses than just blowing buildings up. If we use nukes as EMPs, then the ionized air would interfere our enemies communications and their ability to commit cyber warfare. US for the win, (and allies).
Nukes aside, in a modern war the West Will win again, the West is far more modernized and progressive these days that even if Russia, China, and Iran conscripted every man that they could they would be brutalized as they had during WW2 (with the exception of Iran, but religious radicalism doesn't inspire much intelligence). No matter what it will be brutal for both sides, but NATO if united would triumph.
US alone could destroy the whole world with lasers and shortwave machines.
Wishful thinking maybe, but I don't care, still voting for the SCO.
On the NATO side, the US is the only country with proper cyberwarfare systems and EMPs. On this side, China, Russia and India have EMPs, and China and Russia have the most powerful cyber-systems. Thus, this goes to SCO.
It would be hard to say but Russia would handle Europe while the rest (China/India/...) went for the US.
India+China=too many people to kill.
NATO is a collapsing from inside alliance collapsing European powers Britain Italy France Spain Germany compose NATO also collapsing North American power composes NATO sorry NATO doesnt have the motivation of Eurasian alliancem,which has younger military powers like China India or others !
