Any money spent to eliminate terrorists is money well spent.
Right now America has two military enemies: Iran and Russia and one frenemy: China.
When Russia did the same think they are against it and supported the Ukraine whereas Palestine ask for the same but US is supporting and financing the invasion so it shows the double standards of US.
At the end of the day Innocent lives were taken and the money used to finance is also coming from the innocent tax payers working hard and pay tax to government.
