> Do these nationalists always dismantle their nation

That's a very interesting premise.

I can think of a few counterexamples (Franco in Spain, for all the atrocities committed by his regime, Spain unquestionably progressed economically), but in general yes, nationalists are disasters when in power. Of course it doesn't help that often, especially nowadays, the nationalism is just a wrapper for a bunch of grifters that say whatever is needed to get into power (Farage, Le Pen, Trump, Orban, PiS, Putin). So they're just gifting for personal benefit (which explains the dismantling), advertised as nationalism because that convinces the masses.

Russia has unquestionably developed since the 90s, too. Unemployment in 1998 peaked at 13%, and the country was literally falling apart.

Now, only the parts outside the tier 1 cities are falling apart.

Yet they have also gotten involved in a very destructive war that destroyed their fossil fuel markets, made them a pariah and wasted their Soviet heritage military arsenal. Would not count it as development.

While it is true that many Russians might prefer living in a 2019 Russia over a 2025 Russia, you're not going to find a single person in the country who would prefer the 1999 Russia over either of them.

> wasted their Soviet heritage military arsenal

30-year-old arsenals require replacement, and war (even an embarrassing one) is an to modernize them.
