During Hossein Obama's second term, the United States decided to begin a redistribution of its forces, identifying the Pacific region as a priority for protecting its national interests. While this became clear during President Xi Jinping's first state visit to the United States in 2015, signs of this had already been present at the turn of the millennium. Even then, experts predicted that China would overtake the United States economically by 2020 and militarily by 2025. At that time, China's economic growth was incredibly rapid, several times greater than that of the United States.
If we consider all of this from the perspective of US national interests, there is nothing surprising: in an incredibly short time, China has become a true giant, challenging Washington's hegemony worldwide.
Sooner or later, all of this was bound to happen.
The rapprochement between the United States and Russia should have happened long ago! To avoid the long-overdue alliance between Moscow and Beijing.
Serious disagreements between Washington and the EU surfaced back in 2003, following Washington's decision to occupy Iraq.
Through no fault of the Americans, the Europeans, beginning in the 1990s, destroyed their military industries, thoughtlessly sold off their armored fighting vehicles without producing replacements, disarmed and downsized their armies, and so on.
I even remember this somewhat absurd incident from that time: the Netherlands decided to get rid of its top-notch Leopards, several hundred of them. Outside Europe, many countries immediately wanted to acquire these Leopards.
And now the Netherlands wants to lease 18 Leopards from Germany.
Europeans have long been warned of the danger posed by Russia. Russia was then implementing its first State Program for the Rearmament of the Army. But, alas, no one there, except Poland, took it seriously.
Yes, if you were referring to the current dire security situation in Europe, I agree with you.
As for the geopolitical preferences of your country, Brazil, alas

You're right: every state chooses its allies based on its own interests.
