If the offer is made by the IA, and I had a say in the matter, I would absolutely consider it while taking many factors into account. Why not? If there is a solid, very smart plan and there are proven tactics that have great chances of succeeding, then absolutely. I'm not of the "foolish pride" type. This can be used to light a fire under the current heads in charge, to show them that they're not living up to the challenge and the job will be given to someone else while they suffer a demotion. This is the military and the ones responsible for failures must be held accountable. Maybe bring them in for a short period until things are fixed and then send them back. But here's the problem with all this; the current system is not working and that needs to be fixed first and foremost before any other group comes in and it gets destroyed. The intelligence is clearly not doing its job. People can say all they want as to how difficult it is to infiltrate such evil groups and find out what they're planning and then thwart these attacks before they take place, and that's true, but it's not impossible. It's done all the time. And the Egyptian intelligence knows exactly who and what group these scum are part of. These types of attacks take planning and that's when they must be discovered then channeled correctly, no excuses. Like I mentioned before, it's much more difficult to thwart a lone suicide bomber in a market, but a large and coordinated attack like this one? Pathetic, shameful and most of all very sad.
The training and tactics and procedures are complete failures and have been for a while. They're not properly defending these checkpoints or border stops or military outposts with alert surveillance, or creating several stop-gap measures or obstacle courses for security layers. There's a lack of training for alertness of suspicious activity. Lack of creating barriers of separation for protection, more stop-gaps. There's also the issue of the equipment given to these men that are not the right ones to help them effectively thwart these types of attacks. The training is not specific. They don't have much of a chance under present conditions. Have to tell it like it is, sadly.
So without fixing all this, foreign troops will only be thrown to the lions, unfortunately. Sorry for the long post.
