It's already been established the issue is claim fabrication instantly raising world tension. Rather than addressing this and brainstorming alternative solutions you all seem content to play a game of see who can keep world tension low and refer to basic game mechanics as exploits and abuse. I will post a simple idea but I am done replying.
Claim fabrication should not raise world tension in and of itself. Instead the events that pop up could have various options and even be affected by encryption/decryption/radar tech. These could potentially raise world tension, alter national unity, cost pp, etc.
World tension should be divided between "World" and "regional" with smaller countries not playing as big a role to the eyes of empires. A bit like how the league of Nations gave precisely zero &#!@'s about minor conflicts such as the Saudi yemeni war as it involved nobody of consequence to the status quo.
