It may be that it wants to uninstall some kde-plasma-desktop metapackage, not the whole bunch of all kde apps. If it is uninstalled, nothing crucially important happens. Try to remove it with apt if you're running some Debian or Ubuntu flavour.
Thanks. I was at the army. – For me they all look somehow the same. :p
I was searching for Mirage at first. So my first guess, France, was at least correct.
The first panel shows US made weapons such as the M1 Abrams tank, the Patriot surface-to-air missile system (here mounted onto a German made MAN gl truck), M142 HIMARS system (mounted onto a US made M1140 truck), the F-16, the F-35F-15 or a Virginia class submarine, systems that "the US" thinks the European nations will buy when they invest into their military.
The second panel shows European made weapon systems, such as the Leopard 2 tank, the IRIS-T SLM system (again on MAN), the SAMP/T Aster system (mounted onto a Renault 8×4 truck), Saab Jas 39 GripenRafale, Eurofighter Typhoon or the future French SNLE 3G submarine, systems, that the Europeans probably will buy instead.

I would suggest it's the shadow the flame throws onto the coat of the glass maker, as they probably had a light source behind the camera while filming.
You can then either 'install' them with
apt
, which does essentially only mark installed packags as manually installed or use e.g. synaptic for that.
