Iran’s retaliation has exposed the limits of U.S. power: Gulf allies were hit despite hosting American bases, the Strait of Hormuz is shut, and global markets are recalibrating around a less reliable Washington. The war’s political and economic fallout accelerates a shift toward multipolarity — a moment many now compare to America’s Suez.
Trump’s 78‑day cascade of abductions, assassinations, tariffs, and an unauthorized war has shattered what remained of the post‑1945 rules‑based order. With the UN Charter sidelined and sovereignty treated as optional, the Global South bears the brunt — from tariffs to aid cuts to oil shocks — as a multipolar, power‑driven world accelerates into view.
Trump’s Iran war has triggered oil shocks, inflation pressure, and market turmoil, briefly lifting the dollar while undermining trust in the system behind it. Supply‑chain hits, Fed turmoil, and sanctions whiplash deepen global doubts. China, Russia, and energy importers are accelerating moves away from dollar dependence — a shift the crisis may harden.
Trump’s strategy of hemispheric retreat, tariff coercion, and fossil‑fuel dominance is accelerating the very American decline it vowed to reverse. The U.S. has suffered a sharp drop in global soft power, alienated allies through chaotic tariffs, and ceded the clean‑energy future to China. The result is a faster, more chaotic erosion of U.S. influence.
Russia is quietly considering a return to the dollar system, reversing years of anti‑dollar rhetoric. Economic strain, slowing growth, and dependence on China are driving the shift. If Moscow abandons de‑dollarization, the BRICS project looks less like an alternative order and more like leverage — exposing the limits of the bloc’s monetary ambitions.
The global economy is now fully multipolar in production and consumption, yet its financial backbone still runs through a single national currency. That mismatch — a 21st‑century world running on 1944 plumbing — is what BRICS is trying to correct. Not by dethroning the dollar with the renminbi, but by building a neutral clearing system that avoids the trap of replacing one hegemon with another.
The revival of the India–Arab Foreign Ministers’ Meeting after a decade isn’t just a diplomatic reunion. It’s a sign that both India and the Arab world are trying to position themselves in a world where the Western-led order is cracking from within — and where Washington’s reliability can no longer be assumed.
BRICS has evolved from a clever acronym into a geopolitical project large enough to unsettle Washington. Trump’s 2025 tariff threats — and the panic triggered by his Spain “BRICS” gaffe — reveal how seriously the U.S. now treats the bloc. With 20 members and partners, BRICS+ represents a demographic and economic mass that rivals the G7, even if its internal cohesion remains uneven.
The decline of unipolar authority is now evident, particularly highlighted by the US’s absence from the G20 Summit in South Africa. For years, global diplomacy relied on American leadership to resolve crises. However, the situation in Gaza and the West’s isolation at major multilateral events in late 2025 indicate that this era of singular influence is over.
Brazil’s foreign policy is influenced by a unique historical context; unlike many Global South countries with colonial histories, Brazil’s frustrations arise from its exclusion from the leadership of the postwar order it helped create. This ongoing disappointment informs Brazilian diplomacy, fueling campaigns for institutional reform and recognition, reflecting both ambition and insecurity.
