If, and I repeat if, the allegations are true, yes I agree.
But I would also like the IA to take this with PA officers at a senior level to find out just what the heck happened, and why. No military posturing, just a plain face to place frank talk. Perhaps PA just lost control over their soldiers in that raid, perhaps it was an un-authorized patrol, who the heck knows what happens in that part of the world?
In any case the response has to be measured. No point talking about what we're going to do to them if we can't do it. That way we will only end up looking like fools.
