PROJECT SHAMROCK

Opening

Project Shamrock was the NSA's take of international telegrams at the offices of the companies that sent them. It grew out of wartime censorship and, in the committee telling, ran into the 1970s. Church staff wrote that the monthly take could reach 150,000 telegrams. RCA Global, ITT World Communications and Western Union International sat in the paper as the rooms where copies were made. The companies were told it was still a patriotic leftover. The statute the later lawyers wanted was not the statute the shop had.

Shamrock is collection. Minaret, the sister card, is the watch list run against what came in. Keep them next to each other without letting one eat the other. Ford ended the arrangement in 1975 once the committee weather made it impossible to keep as a courtesy.

The spine of the file is a company room and a monthly count. Shamrock is telegram paper. It is not a rumour that no copy left the building.

Timeline

1940s wartime origin. Postwar continuation as a habit between agency and companies.

1960s-70s volume as later counted. Watch lists sit on the take.

1975 Church airs it. Ford shuts the courtesy.

Later FISA is later life. The company rooms are first.

Wartime censorship made company rooms normal. The postwar habit kept the rooms without keeping the war. That is why Church treated Shamrock as a courtesy that had outlived its statute. One hundred and fifty thousand a month is a round figure. It is still a figure a committee was willing to print.

Key figures

NSA owns the requirement and the count.

The telegram companies own the rooms where copies were made.

Church staff own the 150,000 figure as published.

Gerald Ford owns the 1975 close.

Physical and documentary trail

On the paper, the postwar run gives you four hard objects and no empty room.

One: the Shamrock caption and the wartime root.

Two: company participation as named by the committee.

Three: the monthly volume figure Church used.

Four: the 1975 termination. Church Committee account of Project Shamrock, is the public tray.

There is no full public set of the take. There is no page that makes the companies a myth. There is no statute from 1947 that cleanly authorised the habit.

Named companies are the stay-behind. The take in public would finish the volume. Ford's close already finishes the courtesy as policy.

As many as 150,000 telegrams a month were taken.

Competing explanations

An illegal vacuum on American cables. This is the shocked reading. It has a count. It has company rooms.

A leftover wartime courtesy that nobody re-authorised. Also true as weather. Leftover is still take.

Exaggerated numbers. Weak against the committee page.

Hybrid caution. Copies left company buildings. A president shut the courtesy. The statute caught up later.

Later life of the case

FISA and later collection fights. I keep those on the later-life shelf. The company rooms stay first.

Finding

NSA took copies of international telegrams from company rooms for decades after the war, Church put a monthly figure of about 150,000 on the record, and Ford ended the arrangement in 1975. Believe the rooms. A committee does not invent Western Union for a slogan.

What still will not resolve: the take itself in public, or a statute that cleanly covered the habit. Either one would finish the courtesy. The proving object is still those copies, listed, not summarised as a round number.
