Not sure I understand your question?? Are you saying that in 2008 the US was not in serious financial trouble and Obama started more wars?

Obama had to put a massive amount of public money to keep more banks from going under and he made a commitment to scaling back the US involvement in Iraq/Afghanistan. It's took the best part of a decade to recover so for Trump to pop up now and say 'hey look what I've done' is rubbish.
