It's naive to assume that the US would enter into a hot war with China, or that war is the only way countries oppose one another. The most obvious way to 'punish' an uncooperative CCP would be through trade sanctions. If the Chinese government is responsible and the G7 had any interest in coordinating a response, this would put enormous pressure on the CCP, which is dependent on a rising standard of living for its citizenry. Other possible responses would include strengthening China's regional competitors (e.g., India). At a minimum, it could mean the cessation of global research collaboration.
