I do agree with you that Israel needs a sub-tree more than China does, though as i mentioned in my reply, I don’t believe we can meaningfully supplement the tree with enough unique vehicles for gaijin to see it as a feasible option. I am still fine with SG in Israel tree, however there could be potentially better options which bring more diversity (as gaijin calls it) and “unique playstyles” for israel… i have seen options on the forum such as turkey and chile, as well as egypt and other suggestions before, though i am not in a position to judge how good additions they are since i have no knowledge. Singapore would work for israel, but since most of the air tree would be the same pretty much, it would probably be a waste since most of our aircraft would be unlikely to be represented, apart from maybe the hunter, strikemaster and F-5 family. For ground forces there are a handful of additions that could be potentially useful, though other sub trees could probably achieve a more useful and more diverse addition.
Israel is currently very sparse and does require a subtree a lot before china does, but seeing as gaijin is fixed on adding a subtree to every minor nation, it seems china will get its subtree first, whether we like it or not. If this is the case i do think we would achieve more singaporean representation inside the chinese tree. While we do add a few options to middle ranks (of israel), i doubt it will have enough meaning to the higher ranks for gaijin to consider it, considering both air and ground subtrees are always implemented. Gaijin does not tend to spend resources if they are going to add a vehicle (eg. RSAF F16D) with almost identical weapon payload and performance to the tech tree counterpart, and so its probably unlikely we will see any appearance of any of our modern aircraft, with even the F-15SG becoming unlikely in the shadow of both the F-15I and IA. Gaijins focus with subtrees tends to focus on higher ranks from my observations, and we would not make a difference in that regard.
Chinese players largest concern from what i understand is that sg would be added as a quick fix solution, ignoring all of their concerns about vehicle performance and bug reports, as well as domestic solutions, which is a big issue, not just for china, but many other nations too, such as maybe the french tree, which is being bloated with benelux vehicles instead of domestic options (i may be wrong, please correct me if i am). The post released by gaijin seems to carry the tone suggesting that SG would be some sort of quick fix for china, so it is understandable that chinese players are not happy with such a proposal. I too believe that china should get its fixes before a subtree is even considered being added.
Israel has been in a desperate state since its release in terms of vehicle variety, and i firmly think that a different nation would provide it more variety, which is what gaijin tends to seek. I’m glad we can have a respectful exchange, they seem to be sparse around these parts :)
