I think Israel is the big reason of economic default globally because IMF is the holded by Israel and they are attacking on Phalasteen country,and they are murdering them because they are Muslims.
I don't want to be bias but it's not only them that are in a war. Let's just say that in general that these wars are the reasons for these global economies drop. The pandemic started everything when there were no work, no entertainment, no everything except for food, and health industry was there. They've been the industries that have bagged entirely world's wealth by that time. We are for peace and we're not for these wars, we don't like any further war because it means another series of decline, we can't bear it anymore and the startlers should stop it if they care for their own peace.
I think,most world economic powers like USA and Europe countries are silent because they want the same thing. They want to weak the Muslims.
It's not about the religion but I don't think that they're silent. They're even the one that keeps on spreading alliances in their nearest and farthest regions for their own sake and benefit.
The economy of USA is very strong because they always took step against their enemy. Japan stood against USA and USA collapsed Japan two countries. There is a game of power . Who has a stick ,the buffalo is of that . But that should be change and I think it will change in future.
AFAIK, in modern's time both USA and Japan are allies. But to say that economy of USA is strong, many might not agree to you. Their debt is ballooning and there's no way to stop it and that's why they're selling arms all over the world wherever the war might happen.
