Sounds like a similar Jewish story 80 years ago (or most of the last 4000 years). I understand your point of view very well, but you should be the first to understand the other side, too.
Fighting for a place to live.
Speaking for Germany (which I can't really do) I'm sure the vast majority has much more sympathies for Palestinians than for Israel due to Israel settling policies. Your claim 'Palestinians don't matter to anyone' certainly couldn't be more untrue. Not only for Germany.
Question is, what can be done in this complex matter.
That said, you shouldn't be surprised if the sympathies are under review if some brainwashed hateful extremists kill civilians.
Actually I don't think a peaceful sustainable solution can be found in that region. Too much has happened on that soil over thousands of years. Is this Palestine soil or Jewish? Arab? Muslim? What about Jerusalem alone? Which God wills it more?
We would have to relocate Israel somewhere to the US or wait til Greenland is warm enough. But I wouldn't bet much that Sunnis and Shiites would live peaceful together on that soil left by Jews.
Humans act according to their brain structure. It's fundamentally organized in our early years. We should finally start to discuss what we teach our young kids to later have peaceful adults.
Respect instead of hatred and revenge. Job done - theoretically.
I totally understand the other side insomuch as the Jewish people need a place to call home.
I'm totally behind that.
Home should be where it is now, but that should not preclude a viable independent Palestinian state with the right to it's own independent government, currency, defence forces and all the other apparatus that goes to forming an independent nation state.
When that has happened, and then we're the Palestinians, Hamas, Hezbollah, Iran or whoever it is to continue their campaign against Israel then I would be firmly on the side of Israel.
As it is, Israel is the oppressor and the aggressor. It has through it's policy of confiscation, encroachment and settlement building, eviction, expulsion, killing and downright dehumanisation of the Palestinian people, succeeded in creating a system of apartheid where the Palestinians are herded into walled and fenced enclaves and kept on a drip feed somewhere between bare existence and absolute misery at the discretion of Israel.
No people would tolerate and endure this, the Palestinians are no different.
It is the responsibility of Israel and the powers that back it to bring this about rather than use their overwhelming strength to sustain and prolong this injustice, otherwise the outcome will be a continuing cycle of violence resulting in death and misery not only for the Palestinians but too for the Israelis.
