There are several reason why the industry reacted with caution. One, the upturn in business and market share diminished the immediate importance of the issue. Secondly, there may simply an interest in seeing how well the 1992 agreement works before suggesting changes. Thirdly, politicians can as easily screw things up as help, and may actually make more of a mess than help. Fourth, the international interconnectedness of this industry is substantial, and while the aircraft manufacturers may compete, they also collaborate with suppliers and don’t want to disrupt other well functioning international relations. Finally, they realize that Airbus isn’t going to go away, and in many ways it is better to have a healthy competitor that acts rationally than a struggling competitor that may take desperate measures that hurt the entire industry.
