That is complete incorrect. The dollar is used as a reserve currency because it is stable, has a large amount of liquidity in its financial market, it has a stable legal and political system, and the large trade deficit the U.S. runs. The dollar accounted for 60% of foreign reserves and the euro is second place, with 20%. They are followed by the Japanese yen and the British pound. Russia and China are totalitarian governments that artificially control their own currency flows, as does India (controlling currency, not totalitarianism). People don’t want to use other currencies as their reserves because they aren’t stable and reliable the way the US is, not because the US makes them. You see it in the runner up currencies, that are all large economies with democratic stable governments and open financial markets. Brazil, Russia, India, China and South Africa (BRICS) are trying to make their own version of the euro, so we will see how well that goes and how trusted that is as a currency.

> Nowadays europeean countries interventions in Africa are still very similar to proxy wars, despite the EU and all.

I said “It was also to prevent the intra-European military competitions and arms races that fueled interstate wars for the previous 1,000 years”. Intra means inside and interstate means between states. Proxy wars in Africa are neither inside Europe nor are they between states, since they are literally proxies. Since the last two intra-European interstate wars were WWI and WWII, I’d say small scale proxy wars are a step in the right direction.
