The widening Middle East conflict has negatively shifted the trajectory of the war in Ukraine by diverting US attention and reducing financial pressure on Russia.
A key negative change is higher global oil prices, which significantly boosts Russian treasury revenue as they sell more sanctioned oil at higher prices per barrel.
The US administration has relaxed sanctions on Russia (and Venezuela/Iran) in an effort to put more oil on the market and exert downward pressure on prices to help the world economy, despite this aiding Russia's war effort.
European nations are now forced to step up their own efforts to pressure Russia and support Ukraine, recognizing the diminished US focus and the direct threat Russia poses to Europe.
Specific European actions include boarding vessels in the "shadow fleet" of old oil tankers moving sanctioned Russian oil to reduce Russia's ability to sell.
There are notable tensions between the US and EU over the pace and severity of pressure on Russia, as illustrated by a reported exchange between EU foreign policy chief Josep Borrell and US Secretary of State Antony Blinken.
The Middle East conflict creates a potential strategic alignment, as regional nations are interested in Ukraine's experience in countering Iranian drones.
NATO is experiencing significant internal tension, leading to a serious movement toward developing a stronger, more autonomous "European pillar" with its own defense industrial base and nuclear capabilities (UK, France).
The best-case outcome for NATO is that this European capability development ultimately creates a stronger, two-pillar alliance (Europe and US).
