Ok well as far as the need for a coup goes - it has prevented an outside force taking over the country, in the interim. As it was anyone (hostile or otherwise) could have seized a UK MU and started the coup. All eUK MU would have then backed the government, but we would have probably lost, if you consider what is happening to other countries like Serbia. The coup itself was a risk because it could have been hijacked by foreign forces keeping the gov't in power preparing for a hostile coup.
This issue, arguably above all others, is not (in my opinion) a matter for joking because there could still be forces that may move on eUK in the near future.
