Translate the following English sentence to French:
"Who cannot see that in this case we are dealing with the twosome formed by London and Berlin, escorted by their respective henchmen, and who have no concept of their own diplomacy as being distinct from that of Washington, seeing themselves at best as bit-part players."
Qui ne voit qu'il s'agit en l'occurrence du couple que forment Londres et Berlin escortés de leurs affidés respectifs, qui ne conçoivent nullement leur diplomatie comme distincte de Washington, se voyant au mieux comme des comparses.
