Hi, Mia:

Thanks for your e-mail! In response to your inquiry:

1. Yes, you can use the verb "drives." You should say: "conflict that drives the US into another war in the Middle East ...."
2. You should say "cracked down on": "who are now being cracked down on and isolated in Egypt ..."
3. Very good add! Make sure that you write this new sentence like this (pay close attention to the correct use of punctuation in this passage): " Hence, some circumstances in the decision-making process require an immediate and momentous set of actions, and as the saying goes, one "cannot be a little bit pregnant" as far as taking actions is concerned. It's either to be or not to be. "

Thanks, Mia, and please let me know if you have any other questions! :)

Sincerely,
MasterEditor
