Where have they really succeeded? Only Syria at this point.

A somewhat myopic statement. Try the whole middle east. You think only in terms of bombing and soldiers and not coups, not gladio, not blackmail networks, not school of the Americas, not intelligence intrigue, not buying off, not maneuvering pawns into place over decades with tons of shaping on the diplomatic stage and behind closed doors. They control the entire middle east effectively. Vassals, direct proxies, compradors, moderate rebels. All part of achieving the larger goal of regional dominance. Syria was merely an impediment, a stone wedged in the wheels of their plans which has been removed in a more visible way. Syria was a key piece to complete a larger machinery. Iran is on the side and a problem and they'd love to remove it but they can if they wish simply seal it off, isolate it.

As to Russia, there are more goals and wins in play than simply taking out Russia. That was a maximalist win condition. They've achieved other win conditions. Europe has been brought totally to heel, any notions of independence beaten out of them. They're buying tons of US weaponry and energy as well and have lost any hope in the near future of being able to set independent foreign policy contrary to US interests. That is very, very important. It means they must be with the US when the time comes to confront China. They've also of course been pillaging them, hollowing them out with the energy shocks due to the Russia sanctions and decoupling they used Ukraine as a pretext to force deluded European true-believer liberals into committing economic suicide.

As to China tariffs were never the end all be all, they were never meant to be a master-stroke on their own. They're just one more clumsy attempt to shore up the US against the decoupling it has planned as part of the isolate, sanction, fuel instability, and destroy strategy which like many of their strategies has different levels of success. Absolute being the CPC collapses or is overthrown or liberalizes and is shaped as the late USSR was by traitors within. But lesser success is successfully forcing most of the developed world to decouple from China, building a bloc against it and trying to make China's own bloc and influence small and succeeding in doing that as step one with later steps being peeling off members of their bloc and strangling them economically slowly over time to stifle their progress and keep them weakened and no threat to the western world hegemony (with the rest of the world locked into the US bloc of course as part of this).

The US has a ton of things left to bring to play. Ukraine is just one fire they can set around Russia, already they have Moldova in motion, they have Armenia and Azerbaijan as pawns with the former breaking with Russia because of a comprador government and the latter already deeply compromised with zionist airbases that were used to attack Iran.

Circling back to the whole middle east, they effectively have enough control to totally blunt China's belt and road land routes which is critical to encircling, isolating, and cooking them. Sea routes are heavily defended with massive amounts of NATO air and naval bases with troops on strategic chokepoints around the world. The stuff about the Panama canal, forcing Chinese companies out, Trump's talk of Greenland and the arctic passage and control of that, defense of the zionist entity which can help police waterways in the region, island stuff like Diego Garcia for policing access to Africa. And the list goes on.
