He is correct, but only insofar as it being good to do what is necessary is a truism. The assumption, however is the the problem - that you are correct about 'what is necessary'.

When talking up your own righteousness, you might want to make sure that you've got you priorities aligned with the citizens whose interests and values you say you are protecting.
