a “global war on terror” on September 12 was factually correct.

These officials
confuse armed attack with armed conflict. Yes, the United States was attacked,
but until it counter-attacked, until it engaged in significant armed hostilities,
there was no armed conflict. Following the 1993 attack on the World Trade
Center and the attack on the USS Cole in Yemen in 2000, there was no counter-
attack. American and Yemeni law enforcement officials treated the attacks as
criminal acts. After the attack on the US embassies in Nairobi and Dar-es-
Salaam, the United States did counter-attack in Sudan and Afghanistan. There
was, however, no counter-counter-attack. The violent exchange was too inter-
mittent and too short in duration to constitute armed conflict.
The series of Al-Qaida attacks on the United States are legally significant for
another reason, however. While the attacks did not constitute armed conflict,
they did give rise to the right of self-defense against Afghanistan. The right of
self-defense is triggered if an armed attack occurs. Once the right is triggered,
the victim of the attack is allowed to take offensive military force against the
state responsible for the unlawful attack.

Because of the clandestine nature of
terrorist attacks, the victim state will not always know if there is a state respons-
ible for the attack, nor if more attacks are planned, such that self-defense is war-
ranted. In the case of September 11, Al-Qaida had, by its own public admission,
carried out the attacks; the United States made a case that Afghanistan suffi-
ciently supported Al-Qaida so as to be legally responsible for the attacks, and
because of the series of prior attacks and clear and convincing evidence of future
attacks, a case for self-defense could be made.

Hostilities in self-defense began with a US air offensive against Afghanistan
on October 7, 2001. Those hostilities occurred in Afghanistan, not all over the
world. Afghanistan became a theater of war, and the law of armed conflict
applied in Afghanistan. The United States generally did not then behave as if it
were in a worldwide war. There was certainly no expectation that members of
the US military would become lawful targets outside the Afghan war zone. Four
years after the armed conflict in Afghanistan began, the question became,
“When do hostilities end?” The answer depends on the intensity of the fighting
and the measure of control the government is able to exercise – in Afghanistan.
Thus, exchange and intensity are two key factors that separate terrorist
attacks from armed conflict. Another is control of territory. In today’s world,
this means armed conflict always takes place in connection with a state. For this
reason, many scholars say that nonstate actor groups cannot engage in armed
conflict. To engage in significant armed hostilities, a group must control suffi-
cient territory – it must be at least a quasi-state.

When the Oklahoma City
bombing occurred, no one considered it an armed conflict. The same was true in
Yemen, Nairobi, Kenya, Bali, Madrid, Istanbul, Saudi Arabia, Morocco, and
London. The bombers held no territory in those states. The governments were in
control and did not need to use their militaries to fight the bombers. The situ-
ation in Afghanistan in 2001 was different. Al-Qaida was supported by the
Taliban and its military forces. The Taliban refused to end that support. The
