From Sinai to Jericho and Jerusalem? I assume you mean the ancient time from around 3000BC or so. We weren't call Jews back then we were call Hebrews/Israelites/Bnei Israel(Sons of Israel) when we left slavery from Egypt(according to the old testament not me) we got to Canaan and were ordered to cleanse the land from it's inhabitants by God and we slaughtered the citizens of Jericho (if you want to know my opinion then know it not that I or any other Jew of which I know take that as a good thing, it was bad, no need to remain us of that), David bought the mountains of Jerusalem from it's owners and established the city there thinking it would hold there better against a siege. About Jesus I have no clue - never delved much into the story - all I know is that Jesus was crucified by the Romans according to the main steam: He was betrayed by Judas but the discovered Dead Sea's scrolls reveal that Jesus asked Judas to do so and this version was banned and remained hidden for centuries by the Vatican. So there you go.
So you accept that Allah (I hope you understand we worship same God and the difference is only in the prophet) ordered Moses (AS) to implement his system in the world but that implementation was to remove tyrany ,,, this is similar to the fact that removing Hitler was necessary, now if after 1000s year history will be changed as massacre of Germans than will it be right ?
Ok let me tell you how Muhammad SAW and his companion captured Macca, Madina and Jerusalem the three most sacred place on the earth as per well-established facts :
People of Madina invited Muhammad (SAW) by themselves purely based on his excellent teachings ...
At the time of Makkah, there was no actual battle, except few individual skirmish, People of makkah were given following offers:
1) go at your home and close the doors do not fight and we will not touch you.
2) take your belongings with you, there will be no looting in the goods of those who do not fight.
At the time of Jerusalem, it was put at sige as a result of which Christians, surrendered without any fierce battle ...
If you study neutral historical books, then you will find rules of war by muslims were:
1) no harm to women childeren and old people,
2) no harm to private property
3) Before start of war every army was given choice either to accept Islam or to keep their religion but then pay Jizya (a form of tax) and Islamic forces will take responsibility of protection of the area from outsiders.
4) Not a single person will be forcefully converted to the Islam ...
So in such rule of engagement how can you say that Islam implemented by the way of sword, wars for territorial gain were common in that time, and they were against kingdoms not against common people ...
Where do you fine in today's world main stream muslilms supporting terrorists like ISIS or Al-Qaeda, infact muslims are the most greatest sufferer from these organizations, so how can you say that muslims are terrorist, the way I see it, these are criminals, which are using religion to gain their objectives ...
Bottomline is you need to undertand Islam, basic teaching of Islam, call murder as one of the biggest crime to mankind ...
There 2 reasons of terrorim:
1) terrorists are mostly criminals with own hidden agenda
2) the proxy-wars going in Muslim countries since last 4 decades as a result of which brain washing muslims is easy, for example Aghan war was actualy the war of soviet union vs USA, hundreds of thousands of afghan died, so tell me what a father will do when he saw his son died, will hw not take revenge? and in such revenge he will do alot of incorrect things,
Now just consider the number of wars in the region
Gulf war
Iran iraq war
arab israel wars
yemen war
syrria war
afghan war
millions of people died and more will if you dont provide justice ... most of these wars are proxy wars in which price were paid by innocent and current extremisim is by product on instability created in this part of the world mainly by USA and the own tyrant muslims kings ...
