Trump will do anything to save himself, irrespective if the revelations cause safeguarding concerns for others.
By the nature of their work MI6, CIA and other Intelligence organisation need to have secrecy to safeguard their operatives and their informants, otherwise informants will be reluctant to provide any information to any Intelligence agency should there be any opportunity that this will be laid before Trump.
This is not because the information may be incorrect, but will advertise the very nature and identity of their informants and Intelligence performance and procedures.
But with Trump he is the important one and he has no respect or allegiance for anyone else.
These very actions being considered by Trump will restrict and hinder many intelligence operation, which in turn could have very serious effects on any Intelligence organisation to conduct its business. This will eventually mean that many operations currently in force and those in future will not be effective which in turn will lead to many more actions from terrorists.
Trump by his actions to safeguard himself could well create situations where many persons in many countries will be at serious risk of harm and even death.
But Trump is not concerned about any others be they be persons or countries as long as Trump is safe, which a reckless individual and incompetent he is.
