WHAT USA ACHIEVED FROM MIDDLE EAST AFTER YEARS OF FIGHTING ?

WHAT USA &WESTERNER ACHIEVED FROM MIDDLE EAST AFTER YEARS OF FIGHTING?

I THINK NOTHING THEY ACTUALLY ACHIEVED, THEY CAME TO ESTABLISH DEMOCRACY (AT LEAST THEY SAID IT ), BUT POLITICALLY NOTHING THEY ACHIEVED. THE ONLY BENEFICIARY FROM ALL THESE YEARS OF CONFLICT IS ISRAEL AND SOME SAUDI ELITES. BUT WHAT IS THE GAIN OF USA? IN IRAQ, AFTER YEARS OF FIGHTING IT BECAME A CLOSE ALLY OF IRAN.IN SYRIA THEY COULD NOT DEFEAT ASAD, LIBYA BECAME A COUNTRY OF CHAOS, IN LEBANON HIZBOLLAH- BECAME STRONGER, AND IN AFGANISTAN PROBABLY TALIBAN ARE COMING AGAIN TO POWER. EGYPT BACAME AUTOCRACY AGAIN. YEMEN STRUGGLING WITH FAMINE.SO WHAT WESTERNER ACHIEVED POLITICALLY? MAYBE THEY SOLD SOME ARMS, THAT'S ALL. ONE THING THEY GOT IS CURSE OF INNOCENT PEOPLE WHO LOSES THEIR RELATIVES AND BELONGINGS FROM THIS LONG WAR. SOME LOST THEIR LIVES, SOME BECAME REFUGEE FOR LIFE.

NOW ITS THE TIME TO ASK  USA CITIZENS AND TAXPAYERS TO THEIR GOVT, WHY THESE EXPENSIVE WARS FOR YEARS? FOR WHOM THEY ARE EXPENDING TAXPAYERS VALUABLE MONEY. WHAT BENEFIT ISRAEL GAVE TO US  IN RETURN OF TREMENDOUS SUPPORT FROM US. HOW MUCH MONEY GOVT EXPEND FOR THESE WARS AND WHY?

LET'S SEE SOME PICS OF THESE WAR AFFECTED COUNTRIES:

                                                                            LIBYA NOW

                                                                   IRAQ AFTER WAR

                                                             AFGAN WAR STILL ON

                                  SYRIAN PEOPLE BADLY AFFECTED FOR WAR

                    GRAVE FOR YEMENI CHILDREN WHO DIED IN BOMB ATTACK

I KNOW IN POLITICS THERE IS NO PLACE OF EMOTION. BUT USA CITIZEN SHOULD KNOW WHAT ACTUALLY USA GAINING FROM ALL THESE WARS? IS IT MATCH COST-BENEFIT RATIO?
