Its not clear to me whether this will impact all foreign made drones or just those from China. I get that DJI is the core target, but does this mean that a competitor from Europe (ex. Ukraine which I imagine will have a burgeoning drone market, esp for commercial/defense applications) will need a natsec signoff in order to sell a drone in the US?

Edit to add: From additional reporting on the issue, it seems that the answer is yes, it will affect all countries

Won't this place drone users in US in severe disadvantage right at the time when drones of all kinds are being used to provide all kinds of useful services ? In comparison users in countries with better policy planning will reap benefits.

Shouldn't there been some sort of planning for a local company to provide at least comparable products before needlessly wreaking havoc like this ?
