Why do Iranian missiles get stuck in the way?

Why do Iranian missiles get stuck in the way? 

When an Iranian ballistic missile is fired from Isfahan towards Israel, the first thing that tries to hit it is the US military in Iraq, the French Rafale aircraft in the UAE (which Saudi Arabia allows to use its airspace), and the USS Carl Vinson aircraft carrier patrolling the Persian Gulf, which try to shoot it down with the latest missile destroyers. 

If the Iranian missile escapes all these modern weapons, then the Jordanian Air Force and the US military in Jordan, as well as the British Royal Air Force Typhoon and F-35 aircraft from Cyprus, arrive. 

If it escapes all these dragons, the Israeli air defense system Arrow 3 tries to shoot it down in space from a distance of 2,000 kilometers. If they fail, Arrow 2 tries to destroy it as soon as it reaches the Earth's atmosphere, coming from 1,500 kilometers to 500 kilometers. 

Beyond this, a defense system called David Sling pursues it from 300 kilometers to 40 kilometers.

Even if an Iranian missile manages to evade all these systems, it will ultimately encounter Iron Dome. It tries to shoot down the missile at a range of 70 kilometers to 4 kilometers.

Does any country's missile in the world face so many obstacles in reaching its target? And remember that Iran's ballistic missiles are its own, while the weapons that intercept this missile are the pinnacle of the latest technology of the most advanced countries.
