NATO emergency meeting over killing of top Iranian general

Interesting perspective from Canadian Scholars on Iran, I wonder what their source of information is:

"While the regime is expressing outrage and threatens retaliation, Leuprecht and other experts have also wondered whether the Iranian regime was beginning to feel threatened by the popular military leader. Soleilmani operated largely on his own initiative and was also a substantial drain on already stretched Iranian resources. More so however, he was becoming a powerful political force in his own right as evidenced by his chairing the Iraqi cabinet meeting in December. The suggestion is that allowing him to travel to Iraq may have been an acceptable risk for the regime."
