Analyzing Obama's Speech

Ace of Spades comments on a National Review article: 

"There are other neat things, but the best observation, to me, is the fact that when Obama speaks of Israel, he speaks in terms of concrete demands that he, Obama, is laying upon Israel.
When he turns to the reciprocal concessions most urge on Palestine, however, he stops speaking in the command tense, stops speaking of demanding this or that, and simply says that Palestinians will do better if they stop killing Jews.
Not that they must stop killing Jews, mind you, like Israel must stop building settlements; just that hey, it would be better, you know? Or not, you decide.
For contrast, the writer quotes Bush, who was pretty command-tense with Palestinians: They must crack down on terror and dismantle the terror infrastructure.
Perceptive. Obama makes demands on Israel, but makes promises to the Palestinians. Tells you pretty much where he's coming from."
