Some are frightened into complete inaction. Others try to deal with this as anything else. Those in New York City, especially those living or working downtown, have to continue to live with the daily scares, closures, police actions, and smells.
Israel is not the question or even the answer to any question regarding the terrorist attacks. It is an excuse for the failures of the region's leaders to address fundamental and basic questions of governance and providing for the basic needs of the populations. For a region that all but swims in oil, only a few share in that wealth. The rest are poor, barely able to sustain themselves in a very inhospitable climate. True leaders, those that are willing to challenge the status quo of the region and address those basic questions have yet to assert themselves. One can only hope that there is someone out there who can do it before someone like Bin Laden holds sway over the entire region.
I have often said that peace is the only way to defeat terrorism. If you eliminate the underlying sources of dissatisfaction, you eliminate the base from which terrorists feed. They are like vampires, feeding on the inhumanity of humanity. Terrorists cannot be negotiated with. Nations that harbor them suffer from the same problems. The nations harboring terrorists cannot face the fact that they have failed in the basic responibilities of caring for their citizens. Iraq, Iran, Syria, Libya, and Afghanistan are all failed states that cannot address their nations needs and therefore need to find scapegoats for their woes.
Israel is the scapegoat. The US foreign policy is the scapegoat. Other nations are the scapegoats. Everyone except those that have the ability to change the situation.
