[George W. Bush]

Should the U.S. do the same and expel all non-Americans from her territory?

• Illegal aliens: certainly. Starting with criminals (murderers, rapists, child molesters, gang members, drug dealers), then welfare mooches and those who abuse our schools and hospitals
• Legal residents including green-card holders: no. Legal immigration, selectively applied, is always good for America.
• Tourists: no. But we should be much more selective about admitting citizens from or adherents to totalitarian religion or politics (Marxists and Muslims for instance).

America is entirely different from Israel on this matter.
