The disturbing behaviour by the Turkish president is a blatant attack on democracy. If the leader of a democratic state prevents candidates from standing for election by locking them up or disqualifying them, that is an attack on democracy.
Unfortunately for the Turkish air force the UK public likes democracy. It does not like states that lock up journalists, either. Difficult to know but it is not impossible that Brits will choose to support the people of Turkey demonstrating against Erdogan's attack on democracy. Those Brits may press the UK government to suspend arms supply to Turkiye. I don't know how the German public will see things.
The new UK government is re-assessing UK defence needs. In view of the unfriendly words and actions of the new US president (eg attacking Canada, which shares its king with the UK), the UK may order more Eurofighters rather than more F-35. That would give the UK Eurofighter assembly plant work for years and make a Turkish order less important.
What is certain is that by locking up the democratically elected mayor of Istanbul Erdogan has made it less likely that Turkiye will be receiving Eurofighter.
UK and the USA have no problem with Gaza getting glassed and 50K people getting obliterated.
But somehow you people have the audacity to cry Democracy and Human rights.
Its even more hilarious how Westerners and Europeans tie Weapon sales to human rights.
They kill people you really think a bomb chooses who it targets?
