Well that's it then, nations can just nationalize and steal other nation's assets and reserves to give "reparations" or use them to fund their wars. This opens up a Pandora's box of whether assets and reserves placed in foreign countries or banks is ever truly yours and respected, shaking the very foundation of trust where globalization is based upon, causing people to diversify and avoid countries that have a record of doing these types of actions. Imagine China justifying nationalizing every UK assets and reserves based on China as reparations for Opium War and colonization, brilliant.
