Based on my experience criticizing Iraq and Afghanistan for 20+ years here's your canned responses:

• Gas is so expensive now, why did trump attack Iran?

"That's why we gotta win. Finish the job and it'll come down."

• I’m really worried about our country, won’t china take advantage of this?

"China can't beat America. The only advantages they can get is by stealing our technology."

• What if there is a draft?

"I am too old to get drafted, so not my problem."

Being concerned about China overtaking America in some metric really brings out some pretty dorment racism I have found. But there's usually just a 'one more inning' mindset where it'll all turn arpund against all logic and reason.
