Again, you are only focussing on Israel. The reason you have a problem with this is because you are buying into the trope of Jews controlling governments. What they actually do is invite the MPs to visit, raise awareness on local issues and so on. And they lobby, yes, but it isn't sinister.
During India’s devastating second wave of COVID-19 in 2021, Conservative Friends of India played a key role in mobilising UK support. They lobbied the government to send urgent medical aid, including ventilators and oxygen equipment, and coordinated with British Indian doctors and community leaders to raise awareness and funds. Their efforts helped fast-track life-saving assistance to Indian hospitals and strengthened UK–India relations at a critical time - an example of a "Friends of" group making a real humanitarian impact.
This direct contact allows our MPs not just to be informed and educated, first-hand on really important issues affecting the world.
Who do you think our civil servants are? Genuis wizards with a lifetime of travel and diplomacy under their belt? No, most of our civil servants are generally young, never had another job, never been to any of these countries and if you are discussing junior MPs they don't even have access to those.
Without “Friends of” groups, MPs would rely primarily on their own staff and a few other formal and informal sources for advice and insight. They are usually young, stretched thin, and generalists - not specialists in foreign policy or complex geopolitical conflicts.
