Look, most of the warhawks don't care that New York was attacked in the specifics of actual human beings dying. They care that AMERICA was attacked and they want vengeance for it. Those in New York experienced a real attack with real casualties, so they actually have to worry about the consequences of stupid blundering foreign policies.
There are days I feel like putting a map of the US on my website with a big X on Crawford Texas to direct any terrorists away from New York City. No one in the Homeland Security department sure as hell cares about actually helping New York; they're defunding mass transit, one of the key vulnerable targets in the City and giving more money proportionately to Wyoming for security than to NYC. The administration just announced that they were converting their promises for economic relief for the city into funding for a nice high-speed train to JFK airport-- a nice benny for the wealthy jet set in the city even as the rest of the subway system rots and remains vulnerable.
It's all about symbolism, which is why the very non-symbolic deaths in NYC leads to less warhawk energy.
