I struggle to think of a conflict in any of the regions named to be symmetric. Unfortunately, or fortunately?, short of a nuclear war, we are never going to get symmetric war given how integrated the international economy is. Consider the case of Ukraine and Russian sanctions, all but a sham and politicking with Turkey, China, and even US while being at the helm of sanctions, continue to trade directly or indirectly with Russia. Reminds me of the famous line attributed to Albert Einstein that, "World War IV would be fought with sticks and stones" because the WWIII can't be but a Nuclear Armageddon.
