Iran ardently supports Hezbollah, Hamas, and the Houthis with everything to make them persistent in their attacks on Israel.
And they consistently embark on the development of a nuclear program which will take the whole world to convince Israel that it isn't for nuclear bomb development or enrichment and that they would not use it to attack Israel.
Since Oct. 7th, when Hamas undertook a surprise attack on Israel and killed 1195 people, most of whom were civilians, there has not been peace in Gaza. Israel wants the 251 people taken hostage released, regardless of whether they are alive or dead.
For reasons best known to them, Hamas has prolonged the process of releasing the hostages. A decision that has led Israel to engage in a devastating war against Hamas and the Gaza Strip. Houthis and Hezbollah are also drawn into the war, with Iran allegedly accused of being their backers.
Invariably, Iran had to send missiles into Israel when Israel did not heed Iran's warnings that Israel should stop the bombing of Gaza, as it affects the civilian population. Israel feels Iran was more interested in the Hamas warriors hiding behind the civilians than the civilians themselves.
The series of actions that followed led invariably to the open confrontation that is now engulfing the Middle East presently because Iran's development of the enrichment plant to process its nuclear weapons has become a treat according to Israel, to their very existence and they therefore embarked on a comprehensive bombing of Iran to destroy the areas the nuclear factories are located and Iran has since retaliated which has now led to an open confrontation that may see other nations join the conflict.
Why is Iran developing nuclear weapons at this point, and why do they want to annihilate Israel?
Some people think that behind all these imbroglios is a religious undertaking to wipe out any trace of evidence or belief about Jesus as the messiah.
Otherwise, why is it such a problem for them to live side by side in peace in that area?
