My view is that defence spending needs to increase substantially to somewhere between 3-4% of GDP. In most EU Nato countries and the UK this is a substantial amount. Doing it by reallocating won't work in most so some of both is required but primarily broad based tax increases.

A reallocation from current spending to Investment is needed in several countries, although some could borrow more.

An increase in defense spending to 3 or 4 percent of GDP cannot be achieved by simply creating a one-time special purpose fund, or by increasing debt. Unless taxes are raised which is unlikely, given the high taxation level in most EU countries, budget rebalancing is necessary.

There are many increasing returns to scale in defence industries. So more collaboration would be helpful. Diversification in terms of weapons systems is also a good idea since they don't all work equally well. So a trade-off is desirable.

Increased spending does not automatically lead to increased investment in the relevant industries, because procurement may happen in the international market, particularly the US.

There is going to be certainly a lot of idle capacity in industry. But whether 1% (max) extra) GDP on defense will meaningfully affect growth is unclear. I believe the constraints to growth are others (notably energy).

It depends on what that defense spending is on. If, for instance (but sadly not hypothetically), if defense spending means spending on pensions of retired personal, then no.
