Probably, but dictatorship comes as more fundamental. Signing orders is the worst way to do it. You first grow a base thqt would support you, bring them into positions that would strenghten your absolute power. Sure trump is doing that somewhat but i dont think it is happening at fundamental levels. You also need charisma somewhat.

Good thing is, the US has the checks and balances that would make it really hard for him to achieve his potential goal. It takes more than one guy to make it happen.

I have seen it first hand, in Turkey.
