The biggest problem is that these don't seem to be sophisticated attacks. They didn't find a backdoor or install some malicious piece of code...they simply "hacked people" with phishing scams.
I think a great place for the US govt (and Google) to spend money would be to inform people about phishing and how to detect it. Being a savvy internet user, I sometimes forget that these scams that look ridiculous to me might very well look legitimate to someone else.
