US cuts leave 100 soldiers in Estonia

Estonia's defence minister Hanno Pevkur confirmed last week that US troop numbers in his country dropped from roughly 500–700 to fewer than 100 (NV). Days earlier, about 1,000 US soldiers left Lithuania after the Pentagon cancelled a linked armored-brigade rotation to Poland (Stars and Stripes). From the Baltic to the Black Sea, a pattern is taking shape. US troop rotations are temporary deployments, replaced only when Washington orders a successor. That replacement has become unreliable. European allies are building workarounds at speed, but none can produce the one thing that matters most: a political decision in the White House to send troops.

Washington holds the switch

US rotational forces in Europe are not legal entitlements. The president sets direction. The defence secretary manages force levels. Commanders in the field carry out orders. When Defence Secretary Pete Hegseth launched a six-month review of US military presence in Europe in June, he placed every eastern-flank rotation inside a single Washington decision cycle. According to Liga, citing the Wall Street Journal, Hegseth considered deeper cuts but the White House blocked them without settling the question. The review remains open, and host nations are left planning around uncertainty they cannot resolve.

European allies can do plenty below that switch. After the Pentagon pulled out some forces, allies filled most of the holes within weeks (AP via Boston Globe). On July 1, the 1st German-Netherlands Corps took over coordination of NATO land forces already assigned to Estonia and Latvia. NATO Secretary General Mark Rutte framed the step as Europeans taking on more of the job of defending Europe by land (NATO, Latvian MoD). Command arrangements, though, move forces that already exist. They don't generate new ones.

Every flank state hedges, and hits the same ceiling

Latvia offered US forces priority access to its military bases and training grounds: preferential scheduling and reception support designed to make American arrivals faster (LA.LV). That reduces friction once Washington decides to deploy. It cannot create the decision.

Lithuania has gone further. Germany is stationing a permanent brigade there, expected to reach about 5,000 personnel by 2027, complete with schools and kindergartens for soldiers' children (Euronews, LRT). This is long-term European stationing, not a rotation cycle. Yet Lithuania's parliament passed a resolution calling uninterrupted US troop presence "an irreplaceable element of deterrence" (Regionų žinios). Even the country with the strongest European hedge says it is not enough.

Romania shows the same logic on the Black Sea. The US halved its troop presence there at the end of 2025 (DW). Bucharest responded by expanding the air base at Mihail Kogălniceanu, where allied forces arrive and assemble before moving east (Digi24). Better runways and staging areas help. But European allies still cannot replace the aircraft, refuelling, surveillance and maritime patrol that make US forces so hard to substitute (AP via Boston Globe).

Germany sits behind all of this as the transit hub for eastern defence. Berlin is drafting legislation to give military transport priority on railways, roads and ports during a crisis (BMVg). The corridors work better than they did a decade ago. Who walks through them remains Washington's call.

Finland captures the limit. Its national defence is among Europe's strongest, and its multinational NATO command in Mikkeli already embeds American and Nordic officers (Finnish Defence Forces). Finnish analysts still judge a quick transition to full European self-sufficiency unrealistic (Yle).

The picture from Estonia to Romania is consistent. European allies are building better command structures, base access, transport corridors and legal frameworks. They cover more gaps than seemed possible five years ago. But a US unit on allied soil ties any crisis directly to Washington. No European command arrangement replicates that signal. Frontline states can prepare the bases, corridors and commands. They cannot supply the political decision that puts a US unit there.
