Uranium enriched to a much higher level can be used in a nuclear bomb, though once 20% has been achieved it is technologically easier to reach that required level of purity.
Eh, there's something to it, but it's not like enriching to 20% automatically means they're trying to build a nuke. And more power to them if they are.
Is that just because 20 is higher than 3?
