Law enforcement recovered an AR-style rifle at the scene of the Trump rally shooting.

Nowhere else in the developed world do people accept such a risk of gun death as they do in the US. The right to bear arms doesn't cover hand grenades and bazookas, and it shouldn't grant people such wide access to ARs either. We're now losing about 40,000 people a year to gun violence: how many deaths would be enough to make us rein it back?

I doubt both of your hypotheticals: you're not presenting any evidence to support them, and, although the US President is possibly the single most politically powerful people on earth, no US President actually controls foreign governments.

You don't HAVE to offer proof, but if you want your ungrounded assertions to be taken seriously, you should. As to your question about Russia, yes, they were engaged in acts of aggression towards Ukraine while Trump was President.

"On 25 November 2018, three Ukrainian boats traveling from Odesa to Mariupol were seized by Russian warships; 24 Ukrainian sailors were detained." Russia was also implicated in a series of international misbehavior: hosting bank-hacking cyber crime, attempting to interfere in the 2018 US midterms, using chemical weapons against foreign targets, varied attacks on Ukrainian sovereignty and shipping, escalating attacks on Syrian targets . . . all while Trump was President.

But he preferred to praise Putin for his suppression of the free press rather than to hold him to any kind of civilized standard, you probably weren't aware of all that. Here's a quick greatest hits of Trump kissing evil foreign autocrats' butts for them:

I'm glad you're aware of what's happening globally now (although I'm perplexed that you're putting words in my mouth about Israel and Nato), but you should read up on what happened around the globe and here at home while Trump was in office -- because that was awful.

I meant you as in most liberals, not you specifically, I’m evidently not the best with words. I quite honestly don’t have anything against you or any other person siding with democrats, but I think that it’s entirely stupid that it’s “karma” that Trump was nearly assassinated with an AR because they’ve stuck around and not been banned because it is unconstitutional. I think it is absolutely retarded that some people are perfectly fine with him dying, and even make jokes about it just because they don’t like him. It’s not karma, it’s the fact that Joe said that Trump is hitler, and he’s gonna be a dictator, and all of this demeaning stuff that makes people think he’s gonna bomb America or something drastic like that, which isn’t true. THAT is why he was almost assassinated, not because guns are still allowed EVEN AFTER he is no longer president. I don’t have anything against you, but I’d rather not have to find anywhere I go people saying he deserved to die, that’s not okay, on any front. The only people I would be fine seeing that about is people like Hitler, Kim Jong Un, Putin, people who actually did something to deserve it, and didn't just do something that some people disagreed with. Our country, regardless of the rest of the world, and regardless of what Trump said, thrived when he was in office, and you cannot deny that. The economy, the employment rate, the violence, every aspect I can think of was great. I’m not gonna continue sitting here and arguing with you through my phone wasting my time.

I agree that political violence is unacceptable. However, in a country where we now have a lot more guns than people, almost any unhinged person (or a normally together person having their worst day) can kill or hurt a lot of people. The Second Amendment shouldn't mean that we are all armed with military-grade weaponry without any training or checks, any more than we would still consider Native Americans to be 3/5 of a person.

And think about what the attached graph says about our society: are we okay with that many children being shot every year?

Uh huh, but how much worse than now? A lot? Was it as terrible as now? Because I know life was so much easier and far better before Covid and before Biden became president. Also I didn’t put words in your mouth about Israel or NATO, I’m saying the majority of Liberals call Israel terrorists for defending themselves in a war. If that doesn’t involved you, great. And the only mention about NATO was that Israel was a part of it, I didn’t say you said anything about them.

"So you're the exact same as every other liberal . . . . Israel . . . is pretty much the enemy according to you." Yeah, you did. But I'm glad you support our NATO allies. Trump was pretty shamefully ready to renege on our obligations to them and leave our allies in Western Europe hanging.

[From the Associated Press, a centrist source, during the Trump presidency]

"Donald Trump said that, as president, he warned NATO allies that he “would encourage” Russia “to do whatever the hell they want” to countries that are “delinquent” as the front-runner for the Republican nomination ramped up his attacks on foreign aid and long-standing international alliances. NATO’s leader said Trump’s words could undermine security and put American and European forces at risk."

The vast majority of mass shootings in the US have been done with legally purchased guns.

And the second amendment gives us the right to bear arms, but doesn’t specify the nature of those arms. There’s nothing unconstitutional about banning specific weapons. Hell, it wouldn’t be unconstitutional to restrict us to swords, or tasers and tranq guns.
