Agreed, but still: those in charge did something to fight the crises in the past whereas today those in charge in the best case sit on their hands and do nothing, or in the worst case actively make things worse (e.g. Bolsonaro permitting farmers to blaze away the Amazon rainforest) - and those in power to stop the latter also don't do anything.
Where are, for example, sanctions against Brazilian products like beef that are made on razed rainforest lands? Where are actually impactful sanctions against China? Where are deliveries of MBTs to Ukraine to help drive out Russia? Where are sanctions against Qatar for bribing FIFA and letting thousands of people die in building the WC stadiums? Where is material support for the protesters in Iran fighting against a murderous regime?
Your major misconception is that what you consider good and right aligns with what is politically convenient.
As a nation state, you only have that much political influence, both in the world as well as within your borders, and you will soon find yourself in trouble when people can't afford to eat anymore, or there are no more goods imported from China, or when Qatar gets cranky, or Iran for that matter.
As for Ukraine: The west has no interest in a quick end of the russoukrainian war. It's a perfect testing ground, why stop the fun when you can sell everyone in the neighbourhood so many weapons with the Russian bogeyman getting beaten up with western technology in full view? This conflict will be perpetuated as much as possible, at least another year, after all, Ukrainians do not vote in US elections, but Lockheed Martin engineers do. War is good for business. We all know that, but we like to conveniently forget about that, because our own wallets are closer to our hearts than some kid dying in a trench on the other side of the globe - and that has been true since forever.
