It demands a vote on leaving; at 100 it takes power and the member leaves, unless it pays for a grand coalition.
Every Defence Union member has its own Euroscepticism (0-100, starting at 10-20), which costs up to 15% stability and 20% political power.
Thresholds: at 25 a eurosceptic party breaks through; at 50 it enters parliament, and the member drains the Union's cohesion by 1 a month; at 75 it demands a referendum on leaving; at 100 it takes power and the member leaves, unless it pays for a grand coalition. A Remain vote resets the score to 25 and adds cohesion.
It drifts by itself: +2 a month while Russian money flows, +1 under 40% stability or in a Fractured Union, -1 over 70% stability or in an Integrated Union.
Answers: fund the fact-checkers, spread the cohesion funds, expose the foreign money (it ends Russia's funding and raises Russian Provocation), win a Brussels opt-out (it costs cohesion), ban the party, or call a referendum to settle it.
Russia can Fund the Eurosceptics, then fund a member's party, run troll farms, offer gas discounts and bankroll a referendum once a member is at 65 or more.
