Three former Senior NATO Generals have warned the NATO alliance needs to do more to defend the Baltic.
In a report written in conjunction with a former Estonian defence minister, they say the three countries in the Baltic, Estonia, Latvia, and Lithuania, will eventually need a brigade each to deter Russia - far bigger than the battalions currently being proposed.
It's not however the first time a warning has been issued that NATO couldn’t stop Russia in the near future if it tried to take the Baltics.
However, NATO has started taking steps to address the problem.
They've sent an air policing mission to the Baltics, and in a couple of weeks at the Warsaw Summit, the Alliance is expected to add allied land forces to that package.
But some have voiced concerns about escalating tensions including Germany’s defence minister, Frank-Walter Steinmeier, who says:
"What we should avoid today is inflaming the situation by warmongering and stomping boots."
"Anyone who thinks you can increase security in the alliance with symbolic parades of tanks near the eastern borders is mistaken."
There seems no doubt though that Estonia will get at least a battalion of troops – quite possibly British led.
The real debate in Warsaw will be whether that’s the beginning, or end, of building up forces in the Baltics.
