I always love it when somebody that is ill informed, or one of the 'Russian A/C are super l33t' types come on here and and start spouting things as if they are gospel. I immediately subscribe to the thread, and await the entrance of either Mace or Eagl. Watching somebody argue with two of the best fighter pilots in the world always is good for some out loud laughs. The wife thinks I've gone nuts during these threads, as they have me talking out loud quite often.
One of my best friends from high school, Maj Jason Paquin is a 2000 hour Hornet Pilot here in Canada, and graduated that Empire Test pilot school in the UK where he flew all kinds of Nato fighters, and I think the only modern one he hasn't flown is the F14, due to it retiring. Reading Mace's posts is like listening to him talk.
I was about to jump in about the "no escape zone" of modern NATO missiles, but I think Mace covered it in the above thread far better than I obviously ever could. I will state that if you think that the 95% and higher hit rates from the Aim120 and Aim9 missiles are false, there are a whole bunch of dead Iraqi, Serbian, etc pilots that would argue the point, if they were breathing. Once the target is inside of this envelope, the chances of evading it are pretty much ZERO. Unless the fuzing system completely fails, and the round is a dud, that plane is going to be killed, plain and simple. Even the vaunted Su35 etc with all the flippidy do stuff can never pull enough G, or fly fast enough to escape an Amraam or AIM9m-x once it is inside the no escape envelope. It is physically and mathematically very improbable, and comes down to something failing on the missile, such as the guidance system, warhead, etc. At least this is how I understand the no escape zone.
Now, have the Russians and Chinese made strides in the last ten years. Of course they have. Mainly from stolen information from the look of their aircraft and the word on every defense site on the planet. Have they caught up in terms of technology - no. And more importantly, have their pilots become better than ours? That'll be the day. Of course, China can someday spend enough money to get its pilots the same hours in the air as the USAF/Nato. Even when this day comes, they will have about 30 years of catch up to play to come close to our side's understanding of air combat.
As for the the 70's Cold War match up, why not look at what the Israeli's did with American and Nato equipment and training to the Warsaw Pact's aircraft and training. You have several wars to choose from, from 67, 73, to the late 70's early 80's. I believe the score is something like 20 to 1 or higher as far as air to air combat goes, and even higher if you count the WP aircraft destroyed on the ground. Why would USAF pilots fare any worse vs Soviet pilots in these same plane? Even in Vietnam, towards the end of the war when all of the crazy engagement restrictions were removed, and the F4's could engage beyond visual range at last, look what happened to the Mig21/19/17's then by comparison to the earlier part of that war.
A question for Mace: Do you believe it is worthwhile for the Navy/USAF/Nato to still look at building generation 5/6 type aircraft that aren't focused as much on Stealth, but more on payload, range, maneuverability etc? A plane like the F14/F15/F111 on steroids is what I mean. A really amazing AESA radar, a huge loadout of 12 or more A2A missiles, or an attack variant with about a dozen very useable hardpoints that has huge range. With all of the Stealthy long range missiles coming into service, and not to mention the drones, why even bother with "Stealth" platforms that are manned. Why not build fighters that focus on the other parts of the puzzle like I said, and save a pile of money and build something that sensors and stealth not withstanding is unbeatable in the sky. Now that the Typhoon, Rafale, F35, F22 etc are all here, there doesn't seem to be much coming down the pipe other than a bunch of talk about generation 6 fighters that are super stealthy, and have all the compromises and huge maintenance/deployment expenses like you mentioned.
