Hmmm... I guess I'm just wondering why you didn't attack the AI and dispense with this "Atlantic Wall" tomfoolery?
I guess that in my experience I tend to only be defensive for about the first 50 years or so. The time I tend to get more offensive is when I have the capacity to build impact rovers. At the discovery of Airpower and MMI my aggressiveness increases dramatically. If I have AI enemies within range of my core bases I move to expand my borders by taking those cities in range.
Just off the top of my head you could probably build 2-3 choppers for the price of one mindworm, the same would go for AAA infantry. Not only that, you could build a trained 1-1-1 scout infantry and upgrade just as you could with the choppers. I guess what I'm getting at is that it seems counter intuitive to put so many resources into being prepared to be attacked when you could be putting those resources into staging an attack of your own.

Worse... I only got 1 of the 3 resource restriction lifting techs in the meantime and Lal snatched the WP, so I fell way behind on boreholes and condensors, let alone raising land for an energy park. It's MY 2393 right now and I'm at Shard/Fusion, but I still don't have MMI?! 
...I was University, so I could count on trading Morgan for the build techs (Industrial Automation much later than I would have liked from him, but better then than when the game decides to give it to me!). But I'm getting off topic, if anyone is REALLY interested in my double blind/tech stag experience, I can start a new thread.
