I've seen quite a few SMR proposals over the last couple of years and not a single one that dared to address the whole cycle from deployment to eventual decommission as a function of the total revenues - costs to operate. Most of these projects seem to be made to bilk investors or governments rather than to actually produce power. The day Italy produces the first KWh that is net profitable to the operators without counting subsidies I will be highly amazed, and that's assuming they get to operational in the first place.

Are fossil fuels net profitable after subsidies, wars, and externalities are considered?

I agree, I tell everyone who will listen that no country, not Russia, China, Japan, France, USA etc has ever made nuclear power profitable. And you can't blame it on the environmentalists in China and Russia.

That being said, many countries consider it a national security issue not to be held hostage to foreign oil.

Why does electricity need to be profitable? Are roads, justice systems, or armies profitable?

In most sunny places a decentralized per-home solar policy is cheap, sustainable, and more robust to severe local weather events.

While fission reactors are still the cheaper initial energy choice (like a future cancer patients love of cheap cigarettes.) Small Modular reactors are a fools errand for most places, as they have all the same security, labor, and maintenance issues of full sized installations. Thus, instead of repairing one of four turbines every few years, the contaminated components must now be reprocessed or safely hidden away on mass.

Maybe fine for submarines or aircraft carriers, but for massive infrastructure it is trivial to prove it causes major long-term problems.

Anyone that has ever purchased a property with an old leaky heating-oil tank nasty surprise site-reclamation cost... will understand the initial unit price never covers the actual clean up cost. =3

They didn't because the taxpayers will finance that and no politician would be able to sell this.

Yes, it is part of Trump's tariff deals forced on e.g. Japan:

Italy should be buying proven French technology instead.
