Well if I remember correctly the Iraq invasion take months of preparation beside you should give peace a chance But you are right the door is closing fast with the onset of winter
Going by precedence here is what Neville Maxwell has to say
Despite the growing risk to their sovereignty, Chinese forces in the years prior to 1962 did not engage in conflict with the Indian side. China instead issued a series of warnings and urged India to hold negotiations.
"Those warnings became more and more explicit but constantly ignored until October 1962, the Chinese at last met this constant Indian military pressure with an overwhelming, crushing counterattack."
According to Maxwell, the devastating battle was a humiliation for India's political class and viewed by the Indian government as a stark warning by China.
"(China as the aggressor) was a misconception, fostered of course by India, which put forward the absurd lie that they had been the victim of unprovoked Chinese aggression," Maxwell said.
"But that is not the case, they brought a Chinese counter attack upon themselves by their own wrong-headed border policy."
