in short and to use your pathetic weak and uncreative mytology, if your enemy send you an fake horse, unbuild it and buit it back... why? heheheheh... resaid, why say no to a gift from the enemy? it's a learning opportunity (with all the care regarding all wmds forms, from bio to social) but again the fundamental problem is that it is impossible to be creative in war, the laws of it, aren't of men making... only what's accessible or not.
