"Make America great again"
This, like other instances smells more about making Amercia great, by firstly discrediting non-US products in the home (US) market and allowing the media to spread the FUD around the world. Secondly, by getting the non-US business to open themselves up to inspection by US 'officials' - who we can expect (as this is what happened in the past) to pass information obtained on to US businesses who would normally have had to compete with the non-US companies. Thirdly, the US companies will, having divided the non-US companies (do you trust critical software from a country other than your own?) be able to reconquer the world...
Following this strategy it won't be long before the US regains its 'lead' and hold on the IT sector...
