So how will you know if he changes anything?

The US isn't in anything right now. It's deployed (it always is), but not in active hostilities.

(Unless I'm missing something in Central or South America)

Honestly. No country should have the military spending that the US does. It's too much power in one place. I understand the cold war made it necessary though.

Not ban. Regulate, like food. Have standards and enforce them.

Secondhand nicotine does you no harm. The reason cigarettes are so bad for you is that you're smoking tar. That's what makes the walls of a smokers home yellow, and what gives them cancer.

Nicotine is addictive, but largely harmless at the levels in cigarettes and vapes for the primary smoker. A secondhand smoker will be getting almost nothing. The problem with vapes is, I suspect, the flavourings. I'm aware of mounting evidence that they're not harmless, but I think that's only to primary vapers, not secondary.

I think that last point is an important one.

Banning things often does more harm than good. In your case "Nicotine Bad!" as a policy removes your options.

So regulate them and enforce it.

Oh boo hoo!

People being mildly annoying means they should be banned? Cigarettes were killing smokers and those around them. That's the line for me. If your actions harm others, then it gets restricted.

Vapes are nowhere near that line. They just smell weird.

You know this, but nicotine isn't the problem. It's all the other crap in them.

...and let me guess. Critizing Israel's actions is tacit support of Hezbollah?

Worse than that. Fraud. He's scammed people out of millions.
