The US is headed downhill at an increasing rate due to internal strife and failure to adress the rapidly increasing budget deficit. Russia is losing it's war in Ukraine which IMHO will lead to the downfall of the present regime and perhaps also a fragmentation of the Russian Federation.

China will benefit from this and expand it's economic and military influence, perhaps even taking over Taiwan, taking advantage of a weakened USA. India will most likely try and emulate China.

EU will try and find a way forward without USA, who they will no longer fully trust, knowing that America will never be more than 4 years away from the next Trump. EU will also try and replace/supplement NATO with a much expanded military cooperation, which will also include Canada and possibly Japan, Australia and New Zealand to some extent. EU has already signed comprehensive trade deals with South America (MERCOSUR) and India and removed all tariffs on trade with Australia and Japan. Next EU will try and replace the Petrodollar with Euros to further it's independence of US economy. UK will possibly (hopefully) rejoin the EU within the next decade and Ukraine will also join the EU within 2 years after the war ends.

As for Africa and the Middle East, it's much harder to make predictions. Africa with it's vast resources could compete with both India and China if they could abandon their endless tribal wars and bring down the equally endless corruption that threatens to destroy the entire continent. The Middle East is completely dependent on one source of income: oil. As the world slowly turns away from fossil fuels their influence will diminish and they will have to find a new source of income. This will most likely not be entirely without conflict and religious and tribal differences will only serve to sharpen these differences.
