You cannot blame Starmer, although i respect him for not dragging us into a pointless Iran conflict! Aside from that he is a weak PM.
The facts are there for all to see:
Defence spending has been in decline for many years Between 1992 and 1997 defence spending fell from 3.9% to 2.6% of GDP according to statistics. Then Blair started spending more for military operations in Afghanistan and Iraq (although the funds came from the reserve i believe)
Cameron slashed spending by 8% at the same time cutting military personnel by 12000. He also said tanks would be cut by 40% and heavy artillery by 35%, (not sure if this actually happened)
Now the government has committed to increase defence spending, according to the NATO definition, to 2.5% of GDP by 2027, or 2.6% of GDP when including additional elements of security and intelligence spending. It has since further committed to increase spending to 3.5% of GDP by 2035, in line with a new NATO target. (Trumps demands)
The previous Conservative government had committed to increase defence spending to 2.5% of GDP by 2030.
Interesting

Both parties are shite
Labour have only announced the increases coz Trumpy piled on the pressure accusing europe of relying on the US for defence, which is true
Other european countries are ramping up defence spending big style

It took a couple of weeks to get HMS Dragon ready to sail
One of the main reasons being that the contractors maintaining the ships saw the contracts go from round the clock 7 days a week to Mon-Fri 9-5
I'm 110% that Starmer didn't want it to leave port for as long as possible scaredy cat oooh the ranians might target Britain if its seen to help the US *
& fearful it might get sunk - its supposed to be a f*****g warship !
Me thinks the crew will have been gagging to use it in anger
* note to Starmer - they are anyways terror plots taken down all the time
