It is best if senior politicians avoid comments that are derogatory about their counterparts abroad in case they end up in government. The old rule of do not interfere in the politics of a foreign country usually is wise, unless in government you need to respond in our national interest to actions or statements of a foreign country.
The UK government is led by senior Ministers who ignored these rules when in Opposition. They welcomed President Obama’s endlessly cited intervention in the Brexit referendum for Remain, which turned out to be a clumsy mistake that backfired. They went on to make nasty personal attacks on President Trump which have now come back to haunt them.
President Trump did not intervene in our General election despite their provocations. He has not made personal attacks on them .He is now as an ally and trade partner criticising their energy and industrial policies. This poses a further problem for the government . They had hardly complain about him commenting given their track record.
When President Trump points out US companies are pulling out of North Sea oil and gas investment owing to penal taxes he is stating a fact. When he says a strong economy needs to use more of its own oil and gas rather than importing he is again stating an obvious truth.
Why can’t the government see its energy policy of relying on imports which increase world CO 2 is bad for jobs, for energy security and the environment? Giving away all that potential tax on home produced energy stretches budgets and means the Uk can afford less defence to contribute to NATO where the US assumes a large burden to help us and Europe.
