President Bush, historian:

Likewise, Churchill almost certainly would look askance at the Bush administration's years-long campaign to shut down public debate over the "war on terror" and the conflict in Iraq -- tactics markedly similar to Chamberlain's attempts to quiet his opponents. Like Bush and his aides, Chamberlain badgered and intimidated the press, restricted journalists' access to sources and claimed that anyone who dared criticize the government was guilty of disloyalty and damaging the national interest. Just as Bush has done, Chamberlain authorized the wiretapping of citizens without court authorization; Churchill was among those whose phones were tapped by the prime minister's subordinates.

The rest of the piece isn't all that flattering either.
