Menshevik Defensist here
The Menshivik Defensists occupied the right wing of the party, and for
the most part supported the actions of the Provisional Government. Until
February, they uttered slogans in support of the Fatherland
(in contrast with the ‘Revolutionary Defensists’). The social-democratic
group Unity (Edinstvo), led by Georgy Plekhanov, came out
in favor of ‘war to its successful conclusion.’ The Defensists did not
enjoy support among the masses, or among the Mensheviks.
