Your question is relative since the statement is right wing nut Propaganda.

Their foreign policy is to kill Iraqis, give Cheneys Halliburton a guaranteed no bid $28,000,000,000.00 (28 billion) of taxpayer money to get Saddam when Saudi Arabians were the WTC bombers. But the Bush family is friends with Saudi Royalty. So they get a free pass to kill 3,000 Americans. Yosemite Sam and Dick strike again.

To try and talk things over with the terrorists.
