4. If Israel attacks Iran. US and Russia possible china will be drag to war because its one of their biggest oil supplier.
Meh.
Doubt Israel will do any first attack, they have enough problems as it is, and Iran knows that US will step in if they attack.
If there were to become a conflict, russia might support with equipment, but they will get a deal to get their oil anyways.
Don't think US would risk being tangled up in another war if they can avoid it.
Israel is a very small country, it is smaller than most states in the USA and is surrounded by tons of enemy countries, just open the middle east map to see the sizes. Now, with that in mind, you need to look at the history of Israel and the Jewish people. Every generation there is some nation, at least one, that wants to annihilate all Jews from the face of the earth, this is why a country that is only 65 years old and had so many wars already. Wars with Egypt, wars with Syria, wars where Egypt, Syria, Jordan and Lebanon joined together to destroy Israel and many many more. Just look at the history. Now, as you understand Israel takes threats seriously, as history proved that those threatening to kill Jews, once they are capable or think they are capable of doing so, they act on it.
Just like in WWII the Nazi's decided to kill every Jew on planet earth and did what they did to kill over 6,000,000... So, what I'm getting at here is simple: today Iran keeps on saying (publicly) that they want to destroy Israel completely and remove it from the world's map. While saying that they keep on advancing their nuclear capabilities and once they have that... there will be a time + place in history, once again, where a nation that has intentions on killing Jews will have the capabilities, or think they have the capabilities to do so will emerge.
This means Israel wants to prevent that situation from ever happening, and therefore if Iran keeps going nuclear as they do right now... there will be no choice for Israel but to attack Iran in a defensive attack. Just like when a person tells you he wants to kill you and your entire family, he hates you deeply and then he starts to load a gun... You might tell yourself that as long as he doesn't have a means of killing you, let him talk, but once he has the gun, once he has the bullets and once he starts putting the bullets inside the gun you might want to stop him before he does what he does to you and your family.
So all you need to do in order to know the chances of this scenario happening is to check how far Iran advanced and is advancing with their "Gun-Loading" or in our case - making of nuclear bomb(s).
5. Syria. If Israel attacks Syria. Russia and US will be drag to war.
Meh.
Israel has nothing to win by this, and Syria does not have a proper rule ATM.
Would not be too surprised if there were some border-attacks by Syrian warlords though. But not something that is likely to escalate.
You need to watch the news more carefully. Israel doesn't aim to attack Syria itself, but Hizballah is getting armed by Syria, and as you might know, Hizballah wants to destroy Israel, and already poses amazing arsenal of weapons and arms... Israel must make sure Hizballah doesn't get strategic weapons capable of destroying cities and important factories and areas in Israel country... Again, the size of Israel is very important here, because there's almost no strategic-depth. If a rocket is fired from Lebanon (Hizballah) to Israel, there is no sea, or almost any land for it to fly above... which means the time it takes for the rocket to hit is very short and also it means that less-advanced rockets (rockets that are capable of flying shorter distances, carry less explosives etc) can hurt Israel easily.
Therefore, when Hizballah keeps on threatening to destroy Tel-Aviv, there is the same story here... while they just "talk", let them talk... but once you see they are arming with weapons capable of doing what they want to do... Israel must defend itself and prevent such arms of ever getting to Hizballah.
Therefore, Israel already attack deliveries from Syria to Hizballah and after these attacks Syria... instead of saying they wouldn't give Hizballah weapons and arms... said they will give them their most advanced weapons and they will do it asap! Furthermore, Iran and Russia are backing-up Syria by giving them weapons, troops and diplomatic support but if that's not enough, recently Russia gave Syria s-300 rockets, which are super-advanced anti-aircraft weapons. Furthermore, the officers activating these rockets are Russians and it's already setup in Syria.
This is like saying to Israel to "stop defend itself against weapons and arms delivery to Hizballah by Syria"... but just as you thought it couldn't get any worse, Russia clearly stated that Israel must "stop attacking Syria" which we all know is not "attack" but a pre-attack-defensive measures.
So, just imagine the next missile cargo going from Syria to Hizballah, and I'm talking about chemical weapons and advanced rockets here... Israel will look at the cargo and... what? do nothing?! would you?!? at that point, the cargo delivery will have to be stopped, and then Russia should activate their s-300 missiles, and then we have the beginning of a WWIII.
I have so much more to tell you guys...as I said I can write a book about all this. but I think, it's enough for now. Just look at the nations involved here and go research on your own a little bit. You can come back here and ask questions - I would answer them, mostly.
One more answer to a question asked here before I wrap this reply up:
Who do you think will fight if there's ww3? China/ US?
Generally speaking there will be 2 sides for the conflict, from the one hand we have USA + Many countries in Europe, like France, England, Italy, Ireland etc and also South Korean and Japan and from the other hand we have Russia+China + North Korea + Iran + Syria etc.
If we take a look at a complete list I think we get to about 70 countries involved in this thing... just look at the current Sea-Military-exercise taking place near Iran by USA and 40 more countries together exercising sea-mining removals and attacks from sea.
(Yes, it is taking place as we speak).
