Please do not put words in my mouth that I did not say, I will not entertain that. I am happy to respond to any arguments you make or answer any questions otherwise.
Which part did you not understand?
They're not identical but there are many similarities.
In what ways are they different that it justifies supporting Ukraine but not Palestine?
No one is saying they're identical. But there are similarities.
can anyone rightfully claim it the land belongs to "Palestine"
You should tell that to Israel, which is expelling Palestinians from this land every week for decades. It is not the Palestinians who are claiming the land exclusively to themselves and expelling others from it. It is Israel doing that. I find it crazy that you somehow argue this as if Palestine is doing that.
all this land is my country's, the other country should not exist.
One of those countries is an ethno-religious state that is exclusive of the other. Can you guess which one?
If you are an ethno-religious exclusivist who says "your country shouldn't exist only mine!" and I am a country that multi-religious, and say "actually my country should be the prevailing one, not your exclusivist one", you gotta realize those two are massively different, unlike you portray.
The Russo-Ukranian conflict is clear. One leader is claiming the land of the other
Russia's original pretext for the war is not about territorial gains. It was supposedly regarding Ukraine's attack on Donetsk, Luhansk, and ethnic Russian populations in general (such as the Odessa massacre), what they also called "de-nazification" of the Ukrainian government, and Ukraine's bid to join NATO. This is easily verifiable, but I can provide you a sources on this if you doubt me.
I am not claiming what Russia is saying is true, but it is not what you make it seem to make your argument.
And Israel has a history of propping up Hamas. They even admit it.
Hamas is a militia. They don't have an airforce and whatever else is required to be a military.
I'd urge you to compare the casualties caused by each of the "armies". Hamas is not even a fraction of the concern that Israel is.
Chemical weapons have gone obsolete a while ago. We already know they've had far better stuff for a long time now.
I assume you mean gulf States, cause most Arab States don't have that much oil if any. A lot of them have agricultural economy.
Why are you arguing with me about Russias pretext, as if I'm telling you I support them? I specifically said I don't. Stop deflecting please, and argue my actual point.
