Stephen Walt, professor of International Relations at Harvard, in writing his regular blog on FP, weighs in the now discovered active surveillance program undertaken by the Obama administration, and how that impacts on America's foreign policy:
"And so the circle continues: An exaggerated sense of threat leads to energetic efforts to shape events abroad, even in places of little strategic value. These efforts inevitably provoke backlashes of various kinds, some of which (e.g., 9/11) do genuinely harm Americans. Because it is deemed unpatriotic or worse to even ask what might have led others to want to attack us, officials merely declare that they "hate our freedoms" and launch new efforts to root out enemies. The result is more surveillance, more secrecy, and even more global intervention (e.g., Iraq, Afghanistan, drone wars, etc.) in an endless attempt to root out all sources of "evil." If this gets expensive, then cheaper ways to do it must be found, but what doesn't stop is the open-ended effort to meddle in other countries. This in turn requires even more energetic efforts to conceal what government officials are up to, both to prevent foreign populations from being fully aware of what the United States is doing and to prevent Americans from connecting the dots or questioning the wisdom of the effort."
