President Trump tweeted he will update tge nuclear weapons in the US and the media goes beserk.
President Obama in 2015 sent new smart tactical nuclear bombs in 2015 to Germany and not a stir.
All of the main countries have started a new arm race since 2015, but only now you know it.
Specially China has updated its tactical nuclear arsenal (as there is a treaty between US and Russia banning completely new tactical nuclear system).
Logically US and Russia are craving to leave the treaty as they do not want to fall behind China. And that is what will happen.
