Probably.
A month ago Id have said maybe not as a peace deal would mean spending would carry on as normal.
But now, irrespective of a peace deal it loks like European spending is going to go up and will likely be focussed on European suppliers.
So BAE, QinetiQ, Thales, Rolls Royce, Airbus etc. all set to benefit.
But don't forget peripheral supply chain companies like miners, chemical suppliers, electronics component distributers etc.
This of course, assumes that the Europeans don't throw their hands up in despair and try to blindside the problems. Or just try to hold on for the next president.
Also, possibly US defence spending may fall. SO that may affect many of those companies to an extent.
