President Bush gets it dead right.
The correct response to evil is ostracism, not engagement.
From the Washington Times
Mr. Bush, in his first White House press conference of 2008, described in detail why he thinks the idea of meeting personally with leaders of rogue nations such as Iran, North Korea, Venezuela and Cuba is a bad idea. “It’s a theory that all you got to do is embrace and these tyrants act. That’s not how they act. That’s not what causes them to respond,”
Mr. Bush said. “Sitting down at the table, having your picture taken with a tyrant such as Raul Castro, for example, lends the status of the office and the status of our country to him,” Mr. Bush said. “He gains a lot from it by saying, ‘Look at me, I’m now recognized by the president of the United States.”
