What does lippman find problematic with x's analysis of the soviet union?

Said X misunderstood the sources of Soviet behavior. Much more skeptical that a policy of containment will work. Said we should prepare for the worst (i.e. they are strong) rather than the best (i.e. they are weak)

These islands/chinampas then provided rich soil for crops with easy access to water. i hope this is correct, im so sorry if its not !
