The right is now split into a faction that rejects foreign interventions and wants to withdraw, if not total isolationist then something in that direction, and another faction. At the elite level this other faction is ascendant. The lesson they have drawn from US military failures from Vietnam to GWOT is different from the former faction. In their view the problem is that we were not aggressive enough, we were too constrained by overly legalistic and conservative rules of engagement and various ideological goals which polluted the prosecution of the wars and prevented us from "winning". They DO want a more cruel, more aggressive force posture. They admire and defend Israel in large part because they see it as a model of a force which really believes in "winning". A substantial portion of the voter base is attracted to this, enthused by the prospect of aggressive campaigns in Latin America with relaxed rules of engagement, and sees the renaming to Department of War as a "based" declaration of this doctrine. The country is moving more in this direction and the more isolationist (kind of "Buchananite") wing is getting purged again, but with some concessions made to them.

I am not sure the left has any answer to this right now because it has discredited itself with so many, especially losing a lot of younger men (those under 21 heavily favor Republicans), and generally the country may simply be moving in this direction. I think be clear eyed what you are facing.

National Guardsmen may not find many guns if they arent searching people, but people will think twice about using them with guardsmen standing around. They will get into and escalate altercations where guns might be used less. There are plenty of prior cases where more policing has reduced crime like this, and DC was not doing enough, so this is going to be tried. If the police decide to work together with them enthusiastically, then even more can be done with the extra manpower.

I don't think public perception of police will change much, and anyway it always hovers around 50% confidence in surveys.

Their normal police is very similar to America's in number and capability. They may be trained better, which seems like an argument for better training.

I have the opposite hypothesis: I think more police, even from the NG, will help. I think if our society is more criminal, for whatever reasons, it should be policed more. I do not see any good arguments for how having a few hundred NG deployed will strip me of any important liberty, and I think it is much better than tech solutions in that regard.

We now have a test case, and we can come back and see.

Yes, the US has a high gini coefficient. But the median income is very similar to the netherlands, with NL being maybe 5000$ higher. Median wealth per capita is very similar between the two and Americans have slightly higher purchasing power, although again pretty similar. I don't think crime is higher in the US because rich people are sending the poor into a murderous rage, and if it is so then it just indicates there really is a culture problem.
