About your border skirmishes and possibility of a ground intervention I never spoke about that When there already was a Saudiled invasion taking place you could not argue the way you are doing anyway I even did not speak about Yemeni Fighters Trained in Persian Gulf or something like that Im generally talking about the whole Saudiled intervention or intervention phase of the  Yemeni conflict in historic sense with all its features Yes slowly I got it that you just dont use the meaning of the term military intervention correctly This term doesnt mean just the operations performed by one side maybe you are changing Wikipedia encyclopedia with a military gazette but it addresses to a form of international conflict Military intervention is Interference by a state in anothers affairs by military means That means that both  the operations of the intervening powers and the domestic operations are intermingled Anyway there are domestic reactions to the intervention And youll find no historic literature that tries to separate them because exactly this is the character of an intervention Every singly source dealing with the military intervention in Yemen  deals with both the foreign intervention operation and the existing ground fightings of the domestic conflict Still you did not provide a single source that claims they do not belong together It is your to treat them as separate topics and historic events Greetings
