Let me give you a reminder, this is still happening a lot more often than you would ever realise, it just doesn't get reported.
I really do wish politicians and other civillians would keep themselves out of military strategy and tactics and leave it to those who actually understand it for once.
Now, can you tell me when the last time we actually SHOT at one of the plans encroaching our airspace was? Also, are you trying to say that we need the latest and most expensive planes, and 200 of them, to escort one plane at a time a few times a year back out of our airspace?
You can't do anything without cover, do what? we haven't had to do anything but as that picture shows, escort a couple plans out. we could have escorted that plane out with a freaking Spitfire for gods sake, firstly because that isn't a fighter being escorted and secondly, because they didn't even require firing, but the fact that a 30 year old fighter could have knocked that out of the sky without any effort doesn't exactly back your argument that we need 200 brand new fighters.
Frankly, its a complete waste of money having enough fighters and other things around to wage a war, on the off chance we go to one. Because you'll simply constantly be spending and waste 10'/100's of billions over the decades between wars the equipment is required in.
200 fighters wouldn't be enough on the ridiculously slim chance that the USA, uk, nato went to war with say, China, Korea and Russia, we'd be making them by the dozens throughout a war like that anyhow. For a Iraq/Afghan conflict, 200 is complete overkill also, and overkill for escort duties also.
