Russian propagandists openly state that the situation in the Middle East is beneficial to Russia.

tbf, I don't think there's much doubt in anyone's mind. A missile can be in place A or place B, but it cannot be sent to both.

You don't have to be a Russian propagandist to tell which way the wind blows. The international community is pretty bad at doing two things at once, which is why you barely heard about all the wars in Africa while Ukraine was happening. It would make sense that divided attention would help Russia.

One thing that scares me is that this could lead to China thinking it's the right time to attack Taiwan, creating further global conflict

He's stating the obvious. I already see more headlines about Israel and Gaza than Ukraine. Even the daily article with Ukraine updates was axxed and replaced with Israel+Gaza updates. The Ukraine war was in people's minds for so long because it had a direct impact on prices (mostly food). Now that the prices are going down, Europe has built up a stock of weapons, and fighting might slow down in the winter, there needs to be another shiny conflict the world can feast upon and Hamas delivered it on a silver platter.

Just like climate change, until there's something happening right at our door, we (people) won't give two shits about what's happening abroad.
