You lot do realise that internationals have travelled to Gaza for literal decades, right? Pre-Oslo, under the PA, under Hamas? And that there has just never been any sustained pattern of them being targeted by any Palestinian factions.
Since the 2000s, a total of three foreigners have been killed by Palestinians in the oPt: two were international observers to Hebron and killed in a shooting around a bypass (settler only) road (unclear which faction if any). The third was an Italian journalist and activist, kidnapped and killed in the Gaza Strip in 2010 by some ISIS-affiliated group; this was roundly condemned by all Palestinian factions.
In other words: those are fewer than Israel killed in the WCK strike alone.
Admittedly, I do find the fantasies on this thread re. the heroic IDF rescuing Europeans illuminating - just not quite in the way you probably think: it tells me people have very little actual idea of what these places are actually like, what's safe, what isn't, what the real risks are, etc.
And I'm saying this as someone who has spent ample time in both Israel and the West Bank (and once, very briefly, Gaza).
