You'd have to be quite the ridiculous pseudo-intellectual to claim otherwise. The man was practically an earthly avatar of Postwar Western Conservatism.
The fact that we can have discussions about whether Eisenhower or de Gaulle were conservatives shows how much the political landscape has swayed to the right.
The great conservative leaders of the post war era like Adenauer, di Gaspari, de Gaulle and Eisenhower all had a pragmatic view of the state and its influence on society and they all wanted to move society forward through gradual reforms while protecting the power structure and their national traditions, which is the hallmark of true conservatism.
Modern day radical reactionaries who wants to turn the clock back and dismantle core elements of the state are not really conservatives. Basically a right wing extremist can be a fascist, a libertarian or simply a reactionary, but hardly a conservative. Being pragmatic, having a gradualist approach and a sceptical view of radical change are essential elements of conservatism. A radical conservative is basically an oxymoron.
(of course all conservative parties attract reactionaries, whats different today is that they are able to dominate some of them)
