Just No. Trump knows little or nothing about National Security, Foreign Policy, or US Defense Policy and often neither do any of the folks he appoints. Often other Presidents are lacking in these areas and consequently people with past experience in previous Administrations retain clearances so presidents and government leadership can have access to folks who now have expertise and experience the government can draw from in decision making. Apparently, Trump trust his own expertise and experience beyond that of anyone else. In the job he has now that’s extraordinarily unwise and ridiculous as nobody knows everything. Also, the business acumen he acquired in the business world simply does not translate here.
