put this thread of history through the eye of a needle

[cannonkuo]

Secretary Haig said he agreed, and we must conclude as military men that there is nothing in paragraph 10 that precluded the Argentines from saying that they had obtained satisfaction. We had to put this thread of history through the eye of a needle.

What does put this thread of history through the eye of a needle mean here?

 

[Chasint]

The term "eye of a needle" is used as a metaphor for a very narrow opening. It occurs several times throughout the Talmud. The New Testament quotes Jesus as saying that "it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God". It also appears in the Qur'an 7:40, "Indeed, those who deny Our verses and are arrogant toward them – the gates of Heaven will not be opened for them, nor will they enter Paradise until a camel enters into the eye of a needle. And thus do We recompense the criminals."

Actually that paragraph, although useful, is inaccurate. The expression is not used as a metaphor for a very narrow opening - the eye of a needle is a very narrow opening!

It is in fact a metaphor for performing something very difficult or even impossible.

Whatever was happening with the Argentines (you did not tell us) it was something that would be recorded in history - it seems that the military had to something very difficult.

General Haig was notorious for his idiosyncratic use of language.

Chasint has explained the general meaning - there probably isn't any point trying to analyse it any further than that.
