Let’s imagine China arming and supporting Mexico’s opposition parties that align with China. U.S would go into a fit and invade Mexico instantly. Same has been happening in Ukraine for a decade before the war started. You need to also take in account that Russia has been invaded countless times from western powers. Russia’s geography is also mostly flat plains, making it easy to invade Moscow from the west. Historical context need to be taken to account.

Funny but, just bad advice. Employers will just with someone who has no NDA.
