Italy and the Netherlands aren't rich enough for their own programs, they'd have to piggyback off of someone else's. All the other European states are joining them except the big guys like France, the UK, or Germany in that regard.
Italy, in particular, is
very much rich enough. They are already one of the big three major contributors to the ESA (along with France and Germany, and pointedly
not the UK), and are quite involved in multiple aspects of ESA activity and ISS construction.
The Netherlands is also quite rich enough, by the South Korea standard. Basically, South Korea can do it (admittedly, with imported Russian technology in many critical areas; but so what?), so any country at least as rich as South Korea should be able to do it as well (from the perspective of funding, at any rate; I shall get to technology later). Italy is considerably richer, and I dare say the Netherlands is at least as rich as South Korea.
Maybe? They
are--they have a space program already, and if it wasn't (as I noted) for atrociously bad luck, they'd be in the first list of people who have
already done it.
Brazil and Argentina are likely going to be too much at odds to work together.
Did I say they were working together? No, I said Brazil and Argentina could have space programs. Brazil
does have a space program and, like South Korea, if it weren't for some bad luck they would be on the first list of countries which have done it. Argentina, I'm pretty sure, did have a space program; if the 20th century turned out better for them, it could very well have proceeded (they were pretty rich at the beginning, after all).
Pakistan isn't going to waste R&D on a space program when they have nukes and India to worry about.
But they clearly have the technical and financial capability to do so, as demonstrated by those nukes. Since the OP basically says any POD after 1900 is acceptable, there's no reason to suppose that *Pakistan even has to worry about India (leaving aside, of course, the scenarios where there is no Partition in the first place). Therefore, they are certainly a plausible candidate for developing space launch, given the OP's bounds.
Iraq is also too busy with a space program and its regional rivals to make that significant of a commitment. They would be starting from scratch.
The thing is, they started on it IOTL. Now, admittedly, that was a Saddam project, and likely not too well funded or backed, but given an Iraq that doesn't go through a coup d'etat in the '50s, and may very well be richer for it, it's quite plausible they do something like the Japanese did. It's not particularly hard or expensive to develop a very basic orbital launcher like their Mu series--stacked solid rockets, they didn't even have active guidance!
Saudi Arabia doesn't have the tech sector.
See above. A basic Vanguard-level payload launched aboard a Mu-type rocket takes hardly any tech sector at all. Not to mention the possibility of any post-1900 POD, etc. Or tech importation, a la South Korea or Brazil.
Indonesia is too poor and doesn't have the tech sector.
See above. You are overstating the expense and difficulty of launching a basic orbital payload. Now, most people won't want to do that for the sake of doing it, but nevertheless. I would also note that Indonesia has its own satellite communications network, although it admittedly didn't actually
build the things. Still, with any post-1900 POD there are plenty of scenarios where Indonesia is at least at the Malaysia, if not Brazil, level of development by now.
Egypt lacks the tech sector and Israel (and by extension the USA) might think they're up to something, not Egypt's biggest priority by far.
Again, any post-1900 POD; Israel might not even
exist, in which case what they think doesn't matter. Similarly, they might be far more developed, or conversely have a regime which uses spectaculars to distract from internal problems (a la North Korea; in which case it may or may not work, but they'll give it a shot).
