Westmeath's Declan Power appeared before the Defence and National Security Committee yesterday.
A midlands defence expert feels the 'Triple Lock' is compromising Ireland's foreign policy objectives.

If passed, it would mean only Dail approval will be needed, and the number of troops that can be deployed without a vote would increase from 12 to 50.
Mullingar's Declan Power says the current system has proven an obstacle in the past:
