How does RTW's AI handle deception? Can the ai be tricked into becoming an Allied just for you to turn on "it" once you've move youre entire army in on key positions, such as major income producing cities?

I found this on "Sonshi.com" forum.
was playing Age of Empires recently and decided to put some of what I've learned about deception in the AoW to a test.

I started the match off with myself and one other computer player set to allies. I built up my city and my army and began with my plan. I mentally imagined that I convinced my opponent to allow me to install military units in it's country for it's own protection. After installing several well placed units (each of which consisted of four walls with a gate within which were 10 to 20 soldiers and one or two trebuchets) I amassed two brigades of infantry and archers and put them into ideal positions...

I then broke my alliance with the country and crushed it leaving nothing behind within less than two minutes.

Deception is amazingly powerful...
